KSNI: fix IconThemePath support

IconThemePath is used by a Canonical Patch to enable all Qt apps using
QSystemTrayIcon to transparently provide a SNI with icons exported into
a temporary path. Hence the lack of support breaks icons for all Qt apps
on Ubuntu.

Fix:
- IconItem has a new property themePath which will update a custom icon
  loader
- Use the iconloader to get a KIcon when necessary
- Trigger icon updates when either the source (name/data...) or the theme
  path changes
