Hi devs,

I'd like to propose 2 small changes that should make a huge difference for our
users.

1) Introduce the notion of technical spaces

The idea is that in WebPreferences for a space we should have a boolean property
mentioning if the space is a technical space or not. This will allow to: * Remove the blacklistedspaces variable * List only non technical spaces for simple users

2) Introduce the notion of Application spaces

The idea is that in WebPreferences for a space we should have a boolean property
mentioning if the space is an application space or not. This will allow to: * Replace the Quick Links Panel with an Applications Panel listing all spaces
that are application spaces * Only list Content spaces in the Spaces Gadget in the Dashboard * Add the ability for extensions to declare new applications that automatically
appear in the Applications Panel

I'd also like to suggest adding a global admin preferences to quickly select all
spaces that are application and/or technical spaces (imagine a list of all
spaces with 2 checkboxes for each space listed). This makes it very easy for the
admin to reconfigure what are application spaces (thus showing in the app panel)
and what spaces should be hidden for simple users. Of course modifying these
would modify the WebPreferences of the said spaces.

In addition to make this autodiscoverable I'd suggest that for admins the
Application Panel should have a link to this admin feature. Something like
"Configure Applications...".

WDYT?

Thanks -Vincent

PS: I'm very excited about these 2 ideas since they're simple and IMO will make
XE much easier to use and understand for people starting to use it.
