Rename GUI commands to follow FreeCAD format

[hasecilu]

• Making this change will enable users to use What's this? command on FCGear commands and get the correct Wiki article opened.
• Add missing comma that provoked error.

I make the test saving a file prior the change and opening after it, no problems, anyway someone test it. Since no changes on the names of classes that create the objects were made I think is safe to merge.

Fix #151, #154

[looooo]

Can we change the workbench name to freecad.gears, maybe doing this also for the wiki.

[hasecilu]

I think it's doable, but just admins can do it.
Regarding the capitalization, to make it "fit" to the other pages what do you think about FreeCADGears for the workbench and commands would be like FreeCADGears_InvoluteGear?

[looooo]

is this backward compatible?

is this backward compatible?

Yes, because the classes that create the objects are not changed there is no problems

---

I made some test files before the renaming and opening them after the change seems to not affect them. As long as no properties are modified it's safe renaming commands. Even for scripting the Create* classes are used directly the toolbar commands are not involved.

I have just made this same changes for Fasteners WB and all seems to work fine there also.
Do you prefer FreeCADGears_ instead of FCGear_?
