Pygaming

New pygaming version, with usage of gamarts and ZOCallable for art management. Add cameras, remove windows. Add geometry managers.

The version 0.8.0 is here! Last update includes cursors, encoding, features related to the database and resource management, bug fixes and lot of stuff.

v0.7.0 introduces windows, masks, antialias in drawing, a new template, and the use of a launcher for the built game.
Several bug fixes

The new version introduces lazy loading and transformations for arts. It removes support for pygame.Surface and transform AnimatedSurface into Art. Geometric shapes are now Arts as well. Add transformation classes to transform an art: rotations, scaling, slowing down, set introduction, colors, and combination with other arts ....
The algorithm to get the surface is also modified. Every Element has now a make_surface() method that will create a new surface, and a notify_change() that will make the element's parent that a new computation is needed. This method is called when the surface has changed.
get_surface now has a defined behavior: if has_changed => last_surface = make_surface; return last_surface

The v0.5.0 introduces some new changes:
- A better way to manage sounds: They are loaded in the soundbox at the beginning of the phase and not at game launch anymore. Then, we access them through the soundbox.play_sound('sound_name'). There has also been some improvement in the playlists.
- SoundFiles and MusicFiles have been removed
- Introductions of colors with darken and lighten methods, saturate and desaturate methods, and support for short HTML colors and named colors
- Introduction of the typewriter to manage the fonts and generate the texts. Add support for multi-line texts. Fonts are also loaded at the beginning of the phase and not a game launch.
- FontFIles have been removed
- a few bugs have been corrected
- Speeches are now part of the soundbox
- Texts are now part of the typewriter
