Support of types with dots in their name

I have a rather large codebase using EmmyLua annotations, and some types have dots (.) in them. It seems IntelliJ-Luanalysis doesn’t support that.

This is quite useful when adding annotations to third-party libs for instance.

Example with a Penlight function:

--- Return a list of all file names within an array which match a pattern.
--- Raise dir and mask must be strings
--- @param filenames table|pl.List An array containing file names.
--- @param pattern string A shell pattern.
--- @return pl.List List of matching file names.
function dir.filter(filenames, pattern) end

This fails with the first @param type since the dots isn’t recognized as part of the type name. Same with the return type.

Well it definitely worked at some point, because the annotations were working just fine, so I guess there was a regression some time? Not sure I could tell you when though 😦

Instead of trying to retroactively reserve ., can . continue to be allowed as part of a class name and instead just reserve a different character for literal indexing (# comes to mind, which is used in java) ?
