[Studio] Use of a removed 'org.apache.directory.studio.ldapbrowser.core.model.IConnection' interface in 'ldapbrowser.ui' plugin.xml file

[Pierre-Arnaud Marcelot]

Hi Dev,

When looking at the 'ldapbrowser.ui' plugin.xml file, I noticed that we had a 
warning in various places when it involves the usage of this XML node:
<selection 
class="org.apache.directory.studio.ldapbrowser.core.model.IConnection"/>

This 'IConnection' interface has been removed a long time ago I think.

Should we remove the selection node or replace the class with the 
'org.apache.directory.studio.connection.core.Connection' class ?

Thanks,
Pierre-Arnaud
