Added Check for MultiRomManager

[RecoveryInstaller] added check and alert if the app detects
com.tassadar.multirommgr is installed
[root_tools] the actual package check is here just in case we need to
detect another package in the future
[app.iml] i have no fucking idea
Added custom Image Dumping

[ImageDumping] Custom image via user typing. it checks if the file typed
exists before dumping.
Major Change/Minor Overhaul of ImageDumping

[ImageDumpingActivity] made it list every partition to be available for
dumping. ( May filter it to put things like boot, aboot, recovery, etc
first when available. )
this works on msm and omap partition schemes. It is available on
undetectable partition schemes also but only lists /dev/block and
filters out any partitions with mmcblk in the name.

[SplashScreen] Took out the list of supported devices getting printed to
android log and root_tools.logger()

[strings] took out strings from the old ImageDumping.
I have no idea how to git apparently
Fixed sdcard directory.
Yeah i know i should have done this from the beginning
