Basic if checks so players can't post code or url's/email addresses on titles.
This snippet is to protect website security, MUD security, and player privacy
for those who have a live who list, or anything else that posts to a website.
This can be modified and used in other functions as well.
(I.E.- I also have a custom event adding immortal command which does not allow code or urls
to be posted to the website).
Made it a .c file instead of a text file for enhanced viewing (for code editors, etc.)
Tested and currently used in a modified QuickMUD.
