TG: Some fixes for topic calls and inputs.

There's like 1001 things to fix so some of this is somewhat crude for now.

new helper proc located in procs/helpers.dm
reject_bad_text(var/text)

contains odd characters such as \ / < > or characters reserved by BYOND. It also
rejects if there are no non-whitespace characters)
