This revs. add a new test suite for the im_support module. Defining
a new suite was necessary as the im_support JS feature needs
specific keys to be defined in the session, otherwise its files are
simply skipped.
This rev. adds a new module enabling the livechat support from
the webclient. It allows employee users to communicate with
livechat operators of another database, assuming that a counterpart
addon is installed on that database.
