Project name changed to "bitmask_for_android".
Changed some documentation and scripts.
Looks for correct ndk-build command.

If the build-native.sh script points to a different ndk-build
executable, it uses it.

If not, compile.sh looks for a build-native.sh in the $PATH and, if
present, correct the possible erroneous path in build-native (just to
avoid silly edits in that file), and compiles with it.
Debug does not wipe data.

Minor fixes in the other files.

We need API 15 installed.
leap_android is now bitmask_android
Each step refers to the previous one.

Instead of repeating preconditions, or composing sentences which take some things as obvious (e.g., the android client can be compiled using eclipse, but that does not mean that the run.sh script will work), I refer each step to the previous one.
compile.sh compiles openvpn binaries if necessary.
Shorter README.

Next commit I'll push the Build from eclipse file.

I've also removed the tests .project file because it's not in there, and importing from Eclipse using Git import yielded in an error for the leap_androidTest project.
Added instructions to build from Eclipse.
Link to eclipse instruction in feature/docs

It was pointing to the master branch, which does not contain this file yet.
