Added processing for app window parameters
If the URL contains a "type=apps" parameter, the apps window will be
opened with the default selection. If the URL contains the
"app-category={App Group id OR App Group Name}" as well, then the
corresponding app group will be selected when the apps window opens. To
be specific, the "app-category" parameter will only be processed if
there is also a "type=apps" parameter.
The URL may also contain multiple values, allowing the data and apps
window to be opened at the same time. The order of the "type" parameters
matters with respect to window order within the DE.
