Handle overloaded functions like Angle

[luttje]

Angle supports two ways of calling the function: https://wiki.facepunch.com/gmod/Global.Angle

Sadly we currently only parse one way, which can result in this error:

If the wiki was consistent we could automatically use @overload, but the alternative usage is described in a form that seems non-trivial to parse:

<args>
		<arg name="pitch" type="number" default="0">The pitch value of the angle.


If this is an <page>Angle</page>, this function will return a copy of the given angle.


If this is a <page>string</page>, this function will try to parse the string as a angle. If it fails, it returns a 0 angle.
(See examples)</arg>
		<arg name="yaw" type="number" default="0">The yaw value of the angle.</arg>
		<arg name="roll" type="number" default="0">The roll value of the angle.</arg>
	</args>

Would likely need to hardcode it if you really want people to be able to use that, pretty niche functionality though, if I were to personally use it I'd be fine with adding a diagnostic ignore for the line.

Thanks for your input, this helps me know I'm on the right track. :)

I'll probably hardcode it in the future!

For now I'll use this issue as a call for help to anyone who knows which other functions have overloads like this:

• https://wiki.facepunch.com/gmod/Global.Angle
• https://wiki.facepunch.com/gmod/Global.Vector
• https://wiki.facepunch.com/gmod/surface.SetDrawColor
• https://wiki.facepunch.com/gmod/surface.SetTextColor

I know Color can take strings for whatever reason (since it uses tonumber).

You probably also want to hardcode Color to return a Color instead of table (or maybe their wiki should be changed instead)

Also unrelated to this, probably want to handle default values, since calling Color(1, 2, 3) causes a warning (because of the alpha argument being missing, which is set to 255 by default as per the wiki)

Let me know if I should make these into separate issues

Made into separate issue.

Now trying the extension, same thing that a lot of extensions struggle with is the need to hardcode SERVER, CLIENT and MENU_DLL as boolean?s
