RFC: Change license

[V10lator]

Please don't see this as me trying to force a license change or any other mad action, I'm just trying to start a open conversation with all libgui participants and this seems to be the best place for it.

With that said I think GPL is bad for libraries. Some more liberal license like LGPL or MIT would fit better here. Note that this is my personal opinion, I'm glad to hear yours. :)

If you ever want to change the license note that you need the go from all contributors (or remove all codes of "no" sayers from the project) before doing so. The list of contributors is quite big already, so I think it is a good thing to discuse this before it grows even more:

• @Maschell
• @dimok789
• @dborth
• @orboditilt
• @GaryOderNichts

For the following contributors I'm not sure if their code is in libgui anymore. Someone might want to check on that in case anyone can't be reached or says "no":

• @andriy921
• @z0mb3
• @aliaspider
• @Nougat-Police

The following contributors did nothing in GPL licensed files:

• hosaka-corp (touched the Makefile only: dborth/libwiigui@640e942 )
• coolreader18 (changed meta.xml only: dimok789/homebrew_launcher@9649cbb )

I hope I didn't oversee anyone but please double-check the list of contributors.

Forgot to say: The project already includes LGPL source files ( https://github.com/wiiu-env/libgui/blob/master/source/gui/FreeTypeGX.cpp ). I'm not sure if you're even allowed to mix LGPL and GPL in a single library as one of the two licenses has to define what happens when 3rd party tools access symbols but they define it in a way incompatible to each other.

//EDIT: Ok, mixing seems to be no prob: https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility

It also includes source files with a clearly GPL incompatible license, like this: https://github.com/wiiu-env/libgui/blob/master/include/gui/sounds/Mp3Decoder.hpp
