[pass] [PATCH] Added functionality to retrieve username from a password file and copy to clipboard.

[ged]

This requires a multiline password file with a line for the user as follows:

user: FredFlintstone

Case is ignored. Field seperator is ": " and everything after the field seperator is treated as the username.

Files modified are src/password-store.sh and man/pass.1.
