Universal VRTheme Template

Updated version of the VillainROMTheme Flasher

• Should work on JB, KK, L, MM & N roms by setting folder paths depending on the value of ro.build.version.release in build.prop.
• Selectively wipes dalvik-cache entries for themed apks that include classes.dex
• Creates a timestamped vrtheme_restore.zip in \sdcard\vrtheme-backup\ so that all themed apks can be reverted back to their pre-themed versions.
