TKP_launcher.jar doesn't work for folder names with spaces and returns no error message

Add a validation to check for folder names with spaces. Replace spaces with a character, so that the launcher will function as expected even if the user unzips to a folder they create which has a folder name with spaces in it, i.e. 'TKP Source'

Tested. Works now.
