* Changed way of how "webserverUrl" gets set - any type of data can now be
injected into the egw object by creating an object with the data and an
entry "prefsOnly" set to true. This allows to ensure, that "webserverUrl"
is the first thing that is being set in the egw object (as needed when
including new JS/CSS files at runtime)
jsapi:
* Fixed including JS/CSS files at runtime in other windows than the root
window
* Added "ready" function/module, which provides an alternative to the
$j("ready") function. The ready module provides the functionality to
postpone calling the "ready" until certain events happened.
* using jQuery calendar object instead of jscalendar in the calendar
function.
* added "jquery" module which takes care of including all jQuery modules
in all windows
* added possibility for modules to update constants using the "constant"
function.
* added possibility for modules to access certain other modules using
the "module" function
etemplate:
* Using new egw(window).ready function to build the template first if
loading has finished.
