More Changes Wow

-Started work on what's going to one of 2-3 different methods to load
the values from the SMBXNpc file into the GUI. I'm probably going to end
up changing it so yeah, fun times.
-Modified the texteditor, it now creates a temp.npctxt file to be read
in as if it's a normal file later
-Modified the SpinnerControlValue class to support decimals
-Moved the mime type icons into the resources folder
