Allow users to use the -paste flag to send their data to http://pste.me/with an api key configured. Don't ignore all but the last flag if there are multiple of them. bug 355

Flags were being ignored because they were being stored in a `Map` of some sort as {"Flags": aMatch, "Flags": anotherMatch}, so the last ones were overriding the first one.

Now they're stored as "Flags/drain" "Flags/share" and such.

`-paste` sends the data to pste.me with the api-key and username in the config file, and it should work with the -no-group flag.
