Add GetModuleFile() to the Util functions

[ID99374836576228]

Cloned GetModuleMTime() and return just the name of the file. The function returns the stripped (short name) of the currently running module or empty string if it's a save game.

To note in case it got overlooked in the discord conversation, you can get the module filename with basegame functions. Could be handy for anyone looking to do such without nwnx:

string sModFileName = GetSubString(ResManGetAliasFor("module", RESTYPE_IFO), 12, -1);

Manual test

Module: NWNX-test.mod
OnClientEnter

#include "nwnx_util"

void main()
{
    SendMessageToPC(GetFirstPC(), "Modfile:" + NWNX_Util_GetModuleFile());
}

Result
