Fixed range 1 slider bug issue # 301
Merge remote-tracking branch 'origin/master' into slider_range_one

Improvements to Split block for whitespace and lines:

* Split by whitespace now uses the built-in definition of whitespace \s
  This catches all characters definted as whitespace, see below:
  https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp
* Split a line by all unicode compliant line breaks. The biggest impact here is
  that OSX and Windows files will now split the same way.
The cr option is still around, but ther's no longer a need for it, IMO.
Fixed percent symbols in custom blocks

This fixes issue #476
Set Default Save location to Cloud on Snap! load

location will be the cloud.

Fix reporting out of nested custom C-shaped blocks

REPORT now reports to the nearest lexical element expecting an input
(which may not be the block holding the REPORT statement, this lets you
REPORT out of nested FOR loops).
STOP THIS BLOCK behaves as it used to.
If you’ve been using REPORT instead of STOP THIS BLOCK, you should
migrate.
Treat REPORT blocks inside custom command definitions as STOP THIS BLOCK / IGNORE INPUTS

this also enables all existing FINCH blocks and other hardware
extensions again, which used the REPORT (HTTP://) pattern
