Update to 1.7:

This release uses native File::KeePass support for key files (if
the File::KeePass version is new enough), adds "version" and \ 
"ver"
commands, updates the documentation (as Ubuntu 12.10 now packages
all of kpcli's dependencies), adds a --histfile commandline option,
records modified times on edited records, and adds a -a option to
the show command.
