[Web] URBNG-68 and URBNG-70: Changes in 'Game list' and 'Create new game' views.

- Added 'My games list' view (initial stage). Used static data binded in controller. It will be changed to proper solution soon. Tests for this controller are missing for now but will be provided in next pull request.
- Master template is now divided into two: default (for authorized pages) and home (for other, e.g. home page) because there are major differences between them (home page has to be more 'commerce').
- Set changes in footer. Now it is rendered from submodule file and contains sections recommended by UX team, such as language selector. Switching language does not work properly yet (play application picks language from client's browser by default and there are some problems with binding implicit variables into scalate templates).
- Few changes made by Wojtek in 'Create new game' view.
- Updated menuCtrl.spec and newGameCtrl.spec tests.
