Subject: Introduce -debugnet option, thereby quieting some redundant debug
 messages

Prior to this change, each TX typically generated 3+ debug messages,

	askfor tx 8644cc97480ba1537214   0
	sending getdata: tx 8644cc97480ba1537214
	askfor tx 8644cc97480ba1537214   1339640761000000
	askfor tx 8644cc97480ba1537214   1339640881000000
	CTxMemPool::accept() : accepted 8644cc9748 (poolsz 6857)

After this change, there is only one message for each valid TX received

	CTxMemPool::accept() : accepted 22a73c5d8c (poolsz 42)

and two messages for each orphan tx received

	ERROR: FetchInputs() : 673dc195aa mempool Tx prev not found 1e439346fc
	stored orphan tx 673dc195aa (mapsz 19)

The -debugnet option, or its superset -debug, will restore the full debug
output.
