1.0.8 - The engine underneath gets the mask on every entry

The panel is unchanged. The parser underneath it is not.

The panel computes curves on worker threads, which is what this release is about.
Compiled scripts - the arrangement the accelerator documentation recommends for
evaluating from several threads - ran without the parser's exception mask, so
division by zero raised where the library promises infinity. A parser started
from inside another parser's evaluation, which is what a formula holding Parse
or Deriv does, inherited the caller's mask instead of installing its own.

Name lookup in the parser tables no longer converts the same string to lower case
twice. Deriv costs 3.40 microseconds a call rather than 4.05.

The pascal-mathparser release for 1.0.8 has the detail and the tests.
