Better select filters for ACLs

[fufroma]

xo-* 5.2.1

When I create an ACL, let's say on a Network.

Actually, there is a few way:

• I start typing the name of the network and clic on it. Inconvenient: I have to know my network name, I can't select it.
• I scroll the looooooooong list of Objects. Inconvenient: looooooooong list. Looooong.
• I clic to add all the network and delete. Inconvenient: dummy way.

Suggestion:
When I clic on the "network", button, instead of adding all of them, having a menu with a list of all the network and ability to multi select, with select all and select none link.
