Edited Main class and Method

Simply made the main method create a new instance of LauncherFrame,
which is how the program is run.
Renamed grammarForMessages to be spelled correctly
Added AbstractFrame

AbstractFrame is a frame that the other frames will extend and reduces
duplicate code. Also edited the other frames to extend it and put in
some basic code to make the frames show up (blank)
