[FLASH-USERS] changing maxblocks

[Sean Couch]

Argh.  Don’t do that.  Flash.h should not be edited as it may cause unexpected side effects.  AAAND, you will have to recompile the code anyway so that the new value of MAXBLOCKS is used.  Since MAXBLOCKS appears in a ton of code, the cost of just running setup again is not that much more.

I ran into, what appears to be, a common problem, which is an MPI_Abort caused by a PARAMESH ERROR with the message (in amr.log): New block location exceeds MAXBLOCKS limit
