S2m

Using the -p option when starting s2m did not function correctly.

Default text for Scroll block changed to 'Hello!'.

This release provides a fix for issue 9 and issue 10.

This release incorporates changes to:

1. The micro: bit script s2mb.py was changed to lower the sleep loop and some cleanup performed.
2. The Scratch Write Pixel block was changed to allow variables to be used with its parameters
3. Major changes to the polling architecture were made. These result in lower CPU utilization and better performance in reporting sensor changes.
4. When selecting Japanese using the s2m -l option, you may now specify ja or 1 as the option:
s2m -l 1
or
s2m -l ja

Japanese block translations were added.

This release is a fix for issue 1
