Add a generic "JoinServer" function

[Klemmbaustein]

Adds a function that allows the client to join a server from a ServerInfo struct.
This also changes the server browser to use this function. I have not tested if joining a server with a password works, but it should.

As an example, this is how you'd join a specific server by name:

// Go through all servers that are currently online
foreach ( s in NSGetGameServers() )
{
	// Join the server if it's stupid gun game
	if ( s.name == "Neinguars Stupid Gun Game" )
	{
		JoinServer( s )
		break
	}
}

This builds on top of #688, right?
(just so that I have my PRs in the right order when I finally look at them ^^)

some formatting and optimisations

ty. most of the code with the bad formatting was code i took from elsewhere in the file. printing the server password really is a bad idea though. i don't know why i did that

Code looks good now :)

Merge conflicts atm

Worked!
test by using the function in compartya

altought perhaps there should be a JoinServerByName added in a later pr so that it would be easier to call from plugins :)

Thanks for testing @catornot

@Klemmbaustein can you resolve merge conflicts so that we can consider merging? ^^

[Zanieon]

Code looks good as well so good to go!

Aight this is basically ready to merge. Will be in v1.27.0. The only reason I'm pressing the merge button rn is cause I have a few more fixes lined up and backporting stuff from main to release branches over longer periods of time is pain :c
