Tutorial + configs + transitions + fixes

For the first update of Soliterix I tried to bring some basic stuff the community asked:

Tutorial

The basic tutorial is now live. It teaches the solitaire rules applied to the game, the Joker functionality and how the corners on the screen works. It also shows the game controls for both keyboard + mouse or gamepads.

Configurations

You can now configure the game to best suit your needs: turn the music on or off, change the overall sound volume and set the game to full screen or windowed modes.

Transitions

To make the game more pretty I have included a basic screen transition (fade out/in).

Multiple fixes

I have fixed the mouse usage on the pause menu. Also fixed the mouse dragging controls (to move the blocks).

Have fun! This is the first of many. Updates for life!
