Begins work,
Holopads can receive and send emotes.
The AI, when using 'me', will check if a holopad is being used.  If so, the holopad will output the emote.  If not, it's outputted from the core.
The AI will hear emotes from near an active holopad.
There is a new obj verb called 'see_emote()', that works similarly to hear_talk().
custom_emote() modified to have 'seeing_obj' list.  May be resource-intensive, not sure.
pAIs can now hear emotes, without issue.
Carded AIs can hear emotes, but they hear themselves twice.
Mechs do not hear emotes correctly at this time.
Fixes AI cards/mechs, with least bad method.
I left my debug stuff in.
Resolves conflicts, I hope.
Merge remote-tracking branch 'remotes/upstream/dev' into 12_7_14_holopad_and_emotes
More merge conflict resolution goodness.
Makes the code compile.
Merge pull request #7280 from Neerti/12_7_14_holopad_and_emotes

Adds see_emote(), other cool things.
