[New Feature] Allow multiple entries for BaseUnit=

[Rampastring]

Description:

BaseUnit= only accepts a single entry, which makes it impossible to give different factions different (starting) MCVs without tricky workarounds.

Additional Files:

Kind-of fixed in CnCNet ts-patches: https://github.com/CnCNet/ts-patches/blob/master/src/mods/buildconst_harvesterunit_baseunit.asm

However, as stated in the hack's comments, the hack makes the game replace the unit pointed to by BaseUnit= by a fitting replacement from the HarvesterUnit= list each time the actual base unit is being created. It would be better if BaseUnit= supported a list instead of having this work-around for it.

I would say this is more of a modding bug-fix than a new feature. The programmers expected only one entry in the RULES.INI, so correcting the code to search the vector array just like Red Alert 2 does is the best approach.
