child can be 0 or 1 (or "right" and "left", alternatively)
bbox coord can be 0,1,2 or 3 (or "top", "bottom", "left" and "right", alternatively)
Also added some support for bbox userdata taking "top" "bottom" "left" "right" fields. Not that there's any use for non-node bbox userdata just yet...
Lua sector lines
Adds support for "sector.lines" in Lua, an array containing all the linedefs in a particular sector variable:
#sector.lines returns the number of lines in the sector.
sector.lines\[ _i_ \] (e.g. sector.lines[0], sector.lines[1], sector.lines[2], etc ....) gives you individual linedefs in the sector. If the number you supply is equal to or greater than #sector.lines, this returns nil.
Test script for your benefit: (see comments)
Type "luatest" in console in any level and you'll get a few print messages that tests these features for sectors[0]

BACKPORT: removal of music slots
Relevant commits cherry-picked. Basically everything except the internal music track name switches.
See merge request !43
This fixes how removing certain flags (such as FF_EXISTS) from FOFs can cause HOMs on walls bordering their target sectors. Also fixes how the force-FOF-to-vanish linedef special can leave behind the FOF's shadow
Use whatever names you want for your music. So long as you prefix the lumps with O_ or D_, it doesn't matter anymore.
DISCLAIMER: Linedef type 413 (change music) and Lua scripting is not tested.

This is not how you use pushlstring! This is actually sending uninitialized memory to Lua, which is making scripts have inconsistent results (duh?)
c/o JTE: "Tell Red they're a doofus."
Admittedly I knew of this particular method from the start but wanted to avoid it in favour of a less-hacky looking method of getting sector.lines' size ...but there was none to be found at all.
tmthing must not be set outside of P_MapStart and P_MapEnd
or the game will fail a sanity check which ensures that
mobj references are not persistent across frames and crash.
Angles now go from 0 to 0xFFFF (360 degrees == FRACUNIT) instead
of using a full UINT32. Lua only has one number type, so signedness
gets in the way of using angle_t directly. This handling of angles
matches up with how ZDoom ACS scripting and the like does it.
I also changed all the integer casts and pushes of fixed_t to
their own macro in preperation for possible future seperation.
