[ui] Hide disabled File attributes and their edges but keep the connections

Browse source 
This commit effectively hides a node's attributes when they are disabled.
If these attributes have connections, the edges representing these
connections are hidden but not destroyed. When the edges are hidden, if
one of the connected attributes is still enabled, its pin becomes empty as
if it was not connected to anything.

If the disabled attribute is re-enabled and the connection has not been
broken (if the enabled attribute on the other side of the edge has not
been reconnected to another attribute, for example), the edge re-appears.
If the connection has been broken, then the attribute will be unconnected.

Hidden connections are saved in project files and taken into account when
a project file containing some is loaded.
