Allow the period to be used when playing games.

When I type 'Look at TV.', it says "I don't see that here.", but when I type 'Look at TV', it works perfectly fine, and many people might like the use of a period in the end of a sentence, so please make it usable.

This works in Quest 4 when you include stdverbs.lib, and is a consequence of allowing multiple commands on the command line separated by a period. So to get this working in Quest 5 we just need to implement the same feature in CoreParser.aslx, which should be straightforward - I've added this to the Issue Tracker: http://quest.codeplex.com/workitem/616

The 'look at object.' works, but when I make a new verb and add a period on the end (maybe like 'climb tree.'), it doesn't work.

You could do this yourself by taking the last character of the string and checking if it is a period.
There are built-in functions to manipulate string variables. They're very useful.
