[Android] Initial implementation of the extended info menu.

Most fragments are not implemented yet. This is just a working base framework for it.
[Android] Initial introduction of the EGLHelper utility class. Should simplify all interop with the EGL/GL APIs. Not hooked up yet. However it is entirely functional.
[Android] Finally check if regular OpenGL is possible on devices and display/hide it's fragment based upon this in AboutActivity.java.

Also added another constructor to EGLHelper which can be used to quickly query for information.
[android-about-menu-info] Have information populate the GLES2 and GLES3 tabs.
There is a /lot/ of information in these tabs, we may have to think about changing how the information looks
OpenGL isn't done yet since there are a million limits on desktop GL, may just show a few things and extensions there.
[android-about-menu-info] Add desktop OpenGL tab population.
Since showing every single limit that desktop OGL supports is crazy, Let's just show the basic information, and extensions.
[Android] Greatly clean up the previous commits. Now here is the long list of cleaned up things:
- Spaces -> Tabs | Consistency
- Javadoc everything that was added and not documented.
- Remove duplicated code regarding the adapter that used to reside in DolphinInfoFragment.java. Now it resides in AboutActivity.java without a second duplication of it.
- Properly retrieve all of the contexts in the EGL initialization in EGLHelper.java.
- Remove the attribute EGL_RENDERABLE_TYPE from the pbuffersurface attributes in EGLHelper.java. With this present, the EGL context will always fail to reinitialize if destroyed and attempted to be recreated.
- Break the inner class Limit within GLES2InfoFragment.java, GLES3InfoFragment.java, and GLInfoFragment.java into its own single class. Greatly reduces code duplication.
- Introduce a Type enum into Limit.java (one of the wildly rare cases in Java where an enum is actually an OK solution). Removes duplicated constants from the Java files stated in the previous bullet note.
- Add a copyright comment to the top of EGLHelper.java. Forgot to do this initially, my bad.
- Add some missing override annotations to GLES2InfoFragment.java, GLES3InfoFragment.java, and GLInfoFragment.java.
- Use StringBuilders in the previously mentioned three Java files. This is better than using a String in this instance, as the String object won't have to be recreated multiple times (ala concatenation).
- Fix some constant accessors in the previously mentioned three Java files.
- Added the 'final' modifier to the above three classes and to Limit.java. These classes serve a single purpose only, and are not intended to be inherited.
[Android] Get rid of the version check class in VideoSettingsFragment.java. Not needed anymore since the introduction of the EGLHelper class. Also decouples some classes from the VideoSettingsFragment.java class (yay).

- Minor other change is that the EGL helper fields in GLES3InfoFragment.java, GLES2InfoFragment.java, and GLInfoFragment.java are made final.
[Android] Parse integer ranges in the GLES3 info tab.

The info we retrieve will only ever have 2 elements given back to us.
[Android] Implement CPU info retrieval within the about menu.

ARM only at the moment. Could potentially support x86 and MIPS if necessary.
Capable of parsing the manufacturer codes and part IDs of some (but not all part numbers). If anyone knows of part numbers that aren't in the list, please report them.
OGL: remove version check for buffer_storage on windows

On Windows, nvidia don't give us their driver version, so we can't workaround any issues.
As buffer_storage is broken on some drivers, we wanted to disble it for them.
So we can't.

Luckyly only "some" released driver versions are affected as this extension is only available since some months. Let's hope that nobody have to use one of this driver version, else they will get a black screen ...

Merge pull request #4 from lioncash/android-about-menu-info

Expand the Android app's about menu to include additional info about a user's device.
Upgrade Android API.
Fix three limits in GLES2InfoFragment.java.
Merge pull request #5 from lioncash/android-info-fix

[Android] Fix three limits in GLES2InfoFragment.java.
Change the readme to use markdown instead of being a regular .txt file.
Fix formatting within the Readme.md. A little more.

Properly escaped the underscores in the Windows registry notation.
Update the Readme.md with suggestions and improvements by neobrain.

Updated the "Project Site" link to point to the github page. Also added links to the forums and wiki. Also fixed some list indentation in the system requirements.
Move the recommended CPU/GPU sentences onto their own indented line in the system requirements list (thanks go to neobrain for pointing this out).
Add a period in the system requirements list for consistency.
