Why? Shorter to write and removes the macro usage
I used the following regex to find all occurrences:
```r
RAGE_JOAAT\("(.*?)"\)
```
then the following to replace it all:
```r
"$1"_J
```
* fix(lua): small lua / lau doc fixes: expose stats.get_character_index like intended. also add a bit of doc to button and sameline pages so that the user is correctly refered to the tab class doc
