CMFM: CYAN-200 - Archiving and Extracting .ZIP files in CM File Manager

Added support for zip and unrar commands. Zip, unzip, unlzma, unxz, uncompress and
unrar are now optional. Compress or uncompress of these types are only available
if its commands are present in filesystem

NOTE: This change requires that zip and unrar commands are present in the
filesystem at /system/xbin, which actually don't.

Patchset 2: Rebased
