Configuration option:  Ability to set ERT to be admin call only.

Admin request.

Default behavior is what we're used to, that two heads can call for the ERT
with the option turned on it removes the ability for players to call for an ERT and requires admin intervention.
Optimizes of /obj/New(), by removing access generation.

Previously, every single /obj would parse the req_access_txt and req_one_access_txt strings and turn them into a list of numbers for the access system.
This is now done the first time check_access() is called, so only objects that actually use the system will have the lists generated.

Adds a C library alternative to the ircbot nudge script.

This allows for more secure and stable transmission on Linux, but you might see some improvements on Windows too.
Code lies in (confusingly) lib/src.
nudge.c should be compiled to lib/nudge.[dll/so] and be linked against netutil.c.

There's some horribly hacky code in nudge.c to assemble pickled data, but it's probably the fastest way that's still safe.
