Incompatible servers get dropped from the server list. It
turns out the server list is also used when connecting
directly to a server. This meant that if you tried
connecting to a server that was incompatible, you'd just
get an infinite connection screen, as if the server was
completely unreachable.

Now it won't drop the server if you are directly
connecting to it. I also copied some incompatibility
messages from HandleConnect.

Fix MusicChange hook not returning some values correctly

See merge request !1496

See 7df6a309 and 83a87042. I didn't realize that light
userdata's metatable is shared--like numbers or strings.
So it cannot be paired with a metatable.

I also made a few minor tweaks to Lua cvars, other than
accounting for the double pointer in the userdata.

This reverts commit d4c08a84, reversing

Let Lua cvars use preset values in addition to MIN and MAX

See merge request !1480

Unset zstring if a preset value is used

Closes #487

See merge request !1479

This is only applicable for bounded cvars (MIN, MAX),
since otherwise there's no way to allocate a zstring.

Cvars could now have a range (MIN, MAX) plus some preset
values, but Lua could not take advantage of this due to
table order not being guaranteed.
