Standard Tx Modifications

* Remove contentious sentence about mining non-standard txes possibly
  creating orphaned blocks and loss of block reward.  Suggested by
  @luke-jr (thanks!)

* Remove unnecessary value judgement ("unfortunately") against
  non-standard redeemScripts. Mention that they can be used deliberately
  by someone who wants to easily receive payment to a non-standard
  output script. Suggested by @luke-jr (thanks!)

Non-standard transactions---those that fail the test---may be accepted
by nodes not using the default Bitcoin Core settings. If they are
included in blocks, they will also avoid the isStandard test and be
processed. However, miners who produce blocks with non-standard
transactions put their block reward at risk---if a transaction
produces a bug, the block which includes it will likely be orphaned by
other miners.
