This patch adds support for the `resetall directive. It also changes `celldefine, `endcelldefine and `resetall to no longer grab text following them. These directives do not take an argument so they should not be grabbing any text and silently discarding it. The `timescale processing was reworked to handle being reset and hooks were added to easily change the default time units and precision when we add that feature request.
