Maintenance map editor

[IIYAMA12]

Fixes:

• An issue with unloading the edf (which created a lot of lag when stopping the editor resource)
• Ped armor related (get had to be used instead of set)
• colpath.lua: Not enough checks for nil values
• Wrapper func setPlayerBlipSize was not using the size parameter. Not that it really matters, afaik this function was not being used anyway.
• Making sure that the editor stops edf resources, which didn't do anything before. Although I am not sure how this functionality actually works.
• A typo in matrix.lua (the file was also used in the resource sirenEdit)
• Allow the element lock functionality to be used on edf elements
• Distinct Locked vehicle from Locked selection. I wanted to give it a better name, but the name unselectable didn't fit in the GUI, so I used locked-s instead (When hovering: Locked selection).
