Name bug fix.
Hard-fork is set to happen at block 150000 (~76 days from now). Before that bad name_* transactions are allowed, but won't be processed (i.e. won't be saved to name DB). After that they will be rejected, as well as blocks containing them.

At first start nameindexfull.dat will be rescanned (slow - be patient). If something goes wrong, delete it to force another rescan.
nameindexfull.dat is checked by version (rescanned if below 0.3.72).
