Add keybinds configuration file

[lecler-i]

Delete of Providers config file.
Added a qtwebflix.conf conf file that will have contain the providers and the new keybinds section.

Keybinds

The syntax will be as follow :

action=shortcut

Availabe actions :

fullscreen-toggle quit speed-up speed-down speed-default reload play pause play-pause next-episode

Shortcuts are formatted as in https://doc.qt.io/qt-5/qkeysequence.html (as string literal)

You can give multiple shortcuts to one action, they have to be separated by whitespace ( or \t) :

[keybinds]
play-pause=p
next-episode=> n Ctrl+l t,]

The last example t,] will be a sequential execution of the key t then ].

Providers

As before

[providers]
netflix=http://netflix.com
youtube=http://youtube.com

This is my first time working on a Qt project so check the code troughly, maybe I did some bad stuff that I am not aware of.

Wow thanks for the pull request, I will definitely be taking a look!

I like it a lot but two things.

1. We should have default key binds to play-pause etc. and write them to the conf file if they do not exist.
2. You removed the functionality of the right click context menu it no longer changes the provider.

Hey, sorry for the long time !

I did some little refractoring for better handling of the keybinds.

The issue with the context menu not working anymore is no fixed.

About your point 1., are you sure you want to edit the config file ? It's better we just provide default keybinds in the provided default config file, but overriting / modifying a config file (that is for.. human read) is always a tricky thing and something i personally wouldn't want to happend...
