Make "VM_Create on cgame" error more informative for 64bit ETL

[x0rnn]

Instead of VM_Create on %s failed\n\nMake sure ^2%s ^*exists in the mod's folder you're trying to run and that the mod is compatible with your platform.

Change it maybe to: VM_Create on %s failed\n\nMake sure ^2%s ^*exists in the mod's folder you're trying to run and that the mod supports 64bit clients, else install the 32bit client (applies to e.g. N!tmod, silEnT, Jaymod, NQ)

Or, more general: VM_Create on %s failed\n\nMake sure ^2%s ^*exists in the mod's folder you're trying to run and that the mod supports your platform, else install the 32bit client (applies to e.g. N!tmod, silEnT, Jaymod, NQ)
