reduce jquery files to one

[Marten de Vries]

Currently, the jQuery library is included multiple times inside the OpenTeacher source tree. It would be better if there would be one, which woudl be in its own module 'say type='jqueryLibrary'', which the other modules can require.

This way, it's possible to update the library everywhere at once. Also easier for linux distro's that symlink the library to a system wide installed jquery version.

Of course this does require some changes in the modules using the jquery libraries, mostly copy statements need to be replaced by writing equivalents.

Added modules/org/openteacher/logic/javaScript/libraries/jquery module. Locations to remove it in the source tree (searching for 'jquery' seem to be:
