What changed in EDuke32, build by build

Fix checkavailweapon command.

Fix playervar quick structure access.

CON-solidation

Another attempt at fixing the problems caused by my recent changes to gamearrays

Maybe, possibly, unfuck gamearrays.

ifspawnedby and ifwasweapon are really the same command. Merge the code to execute them.

Syntax changes for gamevar and gamearray declarations:

Remove special limitations on CON customization access to the DNCGS cheat.

Revise some CON VM error messages for consistency. Upgrade a couple of CON VM errors to a new critical error type which pops up a dialog box when the error is encountered. If you've been writing crappy scripts that spam "divide by zero!" errors into the log that you've been ignoring, you're gonna have a bad time.

Some work on CON arrays. Hopefully nothing is broken!

Add support for bitmap gamearrays and expose gotpic to CON

Allow writing to 8 and 16-bit CON arrays

Add OSD_PROTECTED flag, set when gamefunc_Show_Console has been undefined from CON. Currently just requires you hold down shift when pressing the console key to open the console.

When calculating which rotation to use for CON action viewtype 7, offset the frame intervals by 15 degrees instead of 22.5, clearly a copypaste error from viewtypes 5 or 8. Now these are properly centered.

Add wall.blend to structure access.

Add EVENT_PRELOADGAME and EVENT_POSTLOADGAME.

Add drawline256 and drawlinergb commands that call the internal functions used for the automap lines.

Add getclosestcol command, which finds the closest palette index given

Add EVENT_DISPLAYOVERHEADMAPTEXT.

Potential CON performance improvements

Can Duke3D CON version compatibility messages in standalone builds

Gamevar cleanup

Use macros for special gamevar access range checking

Change hard-coded subway effect damage to generic explosive damage that can be handled by CON. Fixes subway kills not counting toward the dead monster count and allows CON scripts to handle subway damage however they like.

Move Mapster32 autoexec to before the map specified on the command line is loaded, to allow EVENT_PRELOADMAP and EVENT_LOADMAP to work when loading a map from the command line. This makes the console output of autoexec a little worse but the OSD will be fixed at a later time.

Handle the save and savenn commands after the full tic is processed, instead of in the middle of it during execution. DONT_BUILD.

Add undefinegamefunc.

Factor out code for launching EVENT_GAME and EVENT_PREGAME.

weapons.con.sample: Use full precision when applying weapon scaling.

weapons.con.sample: Add internal temp variables for rotatesprite parameters that the subroutines need to modify. This fixes weapon scaling.

weapons.con.sample: Rename hud_G_Draw_temp* to hud_int_temp*.

weapons.con.sample: Only setvar RETURN -1 for values of drawweapon that we actually handle. (Currently all of them, but this is more future-proof.)

weapons.con.sample: No need to andvar before getting a sine value. The source does that for us.

Remove bounds check on rotatesprite coordinates.
