Separates the act of creating a TestNode object from starting the node.
The test_framework now keeps track of its list of TestNodes, and test
writers can call start_node() and stop_node() without having to update
the self.nodes list.
A few "a->an" and "an->a".
"Shows, if the supplied default SOCKS5 proxy" -> "Shows if the supplied default SOCKS5 proxy". Change made on 3 occurrences.
"without fully understanding the ramification of a command" -> "without fully understanding the ramifications of a command".
Removed duplicate words such as "the the".
Policy limits (such as chain limits and mempool total size) could reasonably
be enforced more aggressively during a reorg, so use resendwallettransactions
to repopulate the mempool to avoid mined blocks being too small, and increase
the chain limits from the default for this test.
This is in preparation for a change in mempool behavior during a reorg.
