Add partition function

[kingsamurai123]

Added the partition function to 'PluginWindow' class. This function inserts new line breaks, for a specific character offset count. #89

looks on the right track, does calling partition() for plugin description when displaying plugin window not work?

[kingsamurai123]

This is the output if i use 'partition(self.plugin.info["description"])'.

Moving the function into a different function helped fixing the above issue. But not sure if that is recommended or not. What do you think about it?
