Add support for updating local cache through patches
- refactor some code: - code handling the file cache is now in fuse/filecache.c - base36 and base16 encoding and decoding moved to utils/hash.c - mfshell: add "updates" command calling device/get_updates - add container class to store patch information as mfapi/patch.c - apicalls: store more info retrieved by file/get_info - apicalls: add device/get_updates - apicalls: add device/get_patch
