Bugfix: Loading on iOS8 was broken

The loading process on iOS8 was broken because of the
order of the loading scripts. The window.requestFileSystem was not
available while it was called inside the MoodleMobApp.FileSystem.
Removed the deprecated cordova plugin fileSystemRoots
Update android icons and screens

Updated android icons and screens. Cordova 3.6 compatibilty.
Moved the icons and splashes/screens to a new location. This way
they are not included in the final package.
Bugfix: AAI; Better MoodleSession cookies check

The previous check assumed the MoodleSession cookie to be the first
one. This is not always the case. The new mechanism just checks the
MoodleSession cookie presence.
Css fixes

Module name width fix. The whole Modules list section used to
stretch when the title contained long words such as web urls.

Horizontal scroll has been added to Page and Book. The content
some time overflows. Unfortunately it is not easy to scale it
properly.
