More code cleanup and tweaking configurations for MICRO demo

* Tweaks to naming conventions for generating svg files

* Remove redundant logging in SescTherm

* Fix some assertions that were being used to indicate a
  warning rather than an error.

* Remove localTicksUptodate flag because it was triggering
  assertions that were not actual errors

* Reduce max number of instructions simulated to make simulations
  for MICRO tutorial complete more quickly.
