Addon lua docs update and optimising the minimizer when theres no minimizer options enabled.

[Toast732]

• Updates Addon lua docs to be up to date with v1.9
• Made the UI_ID it's own type, that way when people try hardcoding a number with it, it will give them a warning, the reason for doing this is because hardcoding a UI_ID is very bad practice, and is bound to start having issues when another addon is assigned that ui_id, and the two addons start fighting over the ID.
• Optimised the minimizer when theres no minimizer options selected, I did this as I was getting bored of constantly waiting 20-30s when building addons such as Improved Conquest Mode and Improved Missions and AI, and found that by skipping all of the code, heavily reduced the amount of time needed to wait.
• Also implemented the same fix that @OER1057 did, but shouldn't be added with this PR, sorry haha, didn't know you already solved the issue, where the 200 local variable limit in lua would result in you being limited to 64 files, I ended up hitting 65 files with IMAI.
