mgear viewport menu: Range Switch + missing space switch options

[Lohult]

Doing a range switch on any Ik/fk limb causes an error: mgear/latest/scripts/mgear/core/anim_utils.py line 1890: 'NoneType' object has no attribute 'hasAttr' #
It would appear that the tool is not accounting for a namespace. As a test, removing the namespace from a rig allows the range switch tool to function.

Also found another bug where some space switch are missing in the context menu

@Lohult Hi! I know the ticket is old, but I couldn't reproduce the issue with the current mgear branch. can you reproduce the error If you take the latest commit version from the master branch?
For the moment I close this issue with the other fix that I am about to commit. 😄
