override Ext.Components 'validIdRe' to include '@'

we use itemIds with '@' already in the ceph dashboard, and in
non-debug modeit works (as expected) but throws an error
while using ext-all-debug.js so override it to include the '@'

the regex was in place because in html4 the 'id' tag could only consist
letters ofthe mentioned regex, this was lifted in html5 though[0]
