Escaping user defined data

Found a bug that caused bad url requests when you used values
with spaces.

Example: A level name of "My Awesome Level" would cause a url error because the spaces were not escaped.

Also changed the version number to 4.9.1 in hopes that it fixes the new user issue.

It's best if left blank since google by default uses type of page.
Escaping Loaded Level Name

Just in case the loaded level name contains spaces, will replace them with %20.
