Title: Generate locale_date and locale_modified and rename update to modified in filetime_from_git

As is, this plugin wouldn't work default theme because it wouldn't generate locale_{time, modified} and used 'updated' instead of 'modified', i assume this changed at some point and plugin wasn't updated.
