Made lua and love types jumpable

Lua and love types referenced in the docs are now jumpable. To jump to lua types, install the luarefvim plugin.

Fixed issue with altername version of `love.conf`

Now love.conf can be defined in both manners and be highlighted correctly:

-- Newly allowed version
love.conf = function()
end

-- Previously allowed version
function love.conf()
end

Improved documentation generation

Vastly improved documentation generation. Code is now much cleaner and more verbose.
