Expose block filters over REST.

Browse Source 
This adds a new rest endpoint:
/rest/blockfilter/filtertype/requesttype/blockhash (eg
/rest/blockfilter/basic/header/000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f.hex)
which exposes either the filter "header" or the filter data itself.
Most of the code is cribbed from the equivalent RPC.
