Handles spaces in strings provided as CLI arguments.

Now with even more improved bad regex!

Slouching toward 1.0.

Ain't nothing regular about regular expressions.

Adding the ability to use strings as arguments that also contain spaces!

Removed a tracing statement. See previous v0.9.0 notes:

Restores ability to use string literals that evaluate to Pythonic data types. A behavior I've discovered: using arglite as part of a class doesn't seem to allow optional arguments?

Will investigate.

The regular expression describing flags was insufficient for one of the package's primary use cases. This is fixed.

Look, it was broken and I fixed it. Mostly, I made the module jump out of any program that has required args, but doesn't receive anything from the command line. Should've probably been that way before, but I'm not very smart now am I.

Quasi-hotfix for underscores and upper case letters in flag values.
