Close on HOME and Clarify Manifest.

The manifest now explicitly states what the Settings Activity parent is
for older API versions. Making it work properly.

The Activity now just closes when it loses focus. Including the home
button.

This is the basic idea for #53 but still needs to have considerations
for opening things like the camera app.
Created an activity that will allow a user to change a pin code.
Added the action buttons to the pin dialog
Pin dialog now responds to its buttons! Only need to make it so that you can pass arguments and that it returns the pin when ready
The pin fragment can now be interacted with. It should be ready! Just need to finish up the activity to open the app :)
Created a (probably temporary!) widget that opens the pin dialog. The pin dialog cant open the app yet though. Will work on that soon.
YAY! Dialog can now start our activity
Merge branch 'master' of https://github.com/AlexKolpa/AndroidStealth into Pin_dialog

Added the ignore for the thumbs folder
I made the pin manager that will be able to manage the pins of a user. Modified the broadcast receiver to use it too and the pin dialog also uses it now to launch the home activity directly. Also moved the code to launch the activity to HomeActivity.launch where you can launch it but only with the right pin. The broadcast receiver and the pinactivity dialog are modified accordingly.
Now the widget only opens the pin dialog when the user presses 5 times on the widget. Idea: dont just use an amount of times pressed, but use a morse/beat/musical sequence in order to open the pin dialog. Should be unrelated to speed, so one should use percentages of clicks intervals based on the previous.
Added basic first content of the README about the app.
Added instructions for when unclear
Moved to Utils: copyFiles (from content/ContentManager.java)
Added quick read/write methods for text file reading/writing
Added quick randomString and randomCacheFile generators
Moved all references in the ContentManager to our files, to a new class: Directories.java, this class will handle the preferences of our main folder and provides File instances to all our sub directories.
Created the EncryptedPreferences.java class that will replace the SharedPreferences as it will save the preferences in our main folder and will save it there encrypted.
Fix for dot too many. Also added random file generation to given preferred location
Merge branch 'master' of https://github.com/AlexKolpa/AndroidStealth into Pin_dialog

Also cleaned up some code of the encryption part in the contentManager so it fits my current project
