Rename en-pnEqf.mim -> en-pn-eqf.mim and ml-pnC.mim -> ml-pn-c.mim and the icon files

Some other small changes

- remove trailing whitespace
- add standard m17n license header
- add local variables for editing with Emacs at the bottom (makes editing nicer with Emacs because it enables source code colouring
- Put more information in "(descripton (_ …": The description can be displayed by the "input method help" button in the ibus-typing-booster setup tool, it is nice if this shows a bit more information
