Use a correct format string in the unittest JNI wrapper
Fix building the android unittest when targeting older android versions
Remove useless declarations from Application.mk

Remove an unused menu resource file
Remove the stock example icons

at all - there's no need to bundle 8 different extra binary images
just for that.
Change directory to /sdcard before running the unit tests on android

Convert all tabs to spaces in assembly sources, unify indentation

Previously the assembly sources had mixed indentation consisting

Tabs have been interpreted as 4 spaces in most cases, matching
the surrounding code.
