Short description of error
- spacebar search always use english command name and totally ignore i18n translation. This can be sometime useful, but can be a good idea if the user can choose if use original command names or translated ones, similar to "interface/tooltips/new data" buttons (see User Preferences > System > Translation: )
If possible, I suggest to add a 4° button in preferences, as the user can choose if use original or translated command name in spacebar search.
- some panels in Property sidebar in node editor are not translated also if the corresponding string appears translated in the corresponding node box.
Exact steps for others to reproduce the error
