Preconfig: Fix mp_teamlist cvar being set too late

[rtxa]

In Half-Life, the cvar mp_teamlist sets which models are going to be teams, e.g mp_teamlist "hgrunt;scientist". The issue is that HL reads this cvar right before plugin_cfg().

My proposed solution would be to run the preconfig file immediately with server_exec() when the plugin ends so when the map changes, the cvar is already set and the teams will be set correctly. I already tested this and didn't notice any side-effects.

Replace line 841 in file polymorph.sma with:

get_configsdir(szMainFilePath, charsmax(szMainFilePath))
server_cmd("exec %s/polymorph/poly_preconfig%d.cfg", szMainFilePath, g_iNextMod + 1)
server_exec();

Also, I have notice that Polymorph can't read the cvar mp_teamlist properly because it contains semicolons inside which gets trimmed by the next lines.

This get fixed by replacing lines 1039-1041 in polymorph.sma with:

trim(szData);
ArrayPushString(g_aCfgList, szData);
