add support for loading resources

To be used by modules. Could be used for better --install support
(read icon path and real app_name), but as pandora doesn't use it,
I haven't implemented that.
don't hook longjump functions

glibc varsion is incompatible and corrupts stack
allow objects through JNIEnv_NewGlobalRef
add support for key input
properly support standard streams (stdout, ...)

More importantly, makes fprintf work and SuperHexagon can save it's
scores.
get rid of linker_format.c

Main problem with it is that it contains vsnprintf function,
and that gets linked to apkenv's calls instead of more complete
glibc's implementation.
add a module for openFrameworks/SuperHexagon

Super Hexagon is using modified version of openFrameworks
(http://www.openframeworks.cc)
Tested on humblebundle version.
add gitignore
Merge remote-tracking branch 'notaz/master'

Conflicts:
	apkenv.c
