Release 0.8.11 "Accomplishment" - Towards full equation library

This release contains a number of fixes and features intended for use in the
equation library being contributed by Jean Wilson

Features
========

* Accept library items for functionc calls. For example, the expression
  `'ⓁSiDensity(273_K)'` is now accepted. This function is usd in semi-conductor
  equations in the library.
* The `Root` command now attempts symbolic solving using the `Isol` command.
  This can lead to exact solutions for common equations.
* The `SigDig` command is a DB48x extension that returns the number of
  significant digits in a number, i.e. the number of non-zero digits.
* The `xpon` and `mant` now apply to unit objects
* Functions now accept assignments as input, e.g. `x=9` `sqrt` gives `3.0`
* The equation referenced to by the `Equation` variable can now be identified
  using a name.
* The `NxEq` command now works with quoted equations

Bug fixes
=========

* The `ln(1E-100)` expression no longer gives a `Argument outside domain`
  error. The error was caused by rouding during argument reduction.
* Comparison between a value and a unit object now work correclty
* Arithmetic now correctly deals with dimensionless unit objects, for example in
  expression `'1-1000_mm/m'`, and improves the evaluation of unit expressions
  when adding or subtracting unit objects.
* Names containing programs or functions are now evaluated as part of algebraic
  evaluation
* The solver now correctly processes equations wrapped in an expression.
* `Convert` now correclty evaluates its arguments when necessary
* Assignment objects no longer cause a crash on error. For example, `x='ln(0)'`
  no longer crashes.

Improvements
============

* Improve solver heuristic when slope is small. This allows the solver to find a
  solution for an equation like `'tan(x)=224'` in degrees mode.
* Add more recorder entries in the solver describing what is being solved.
* Move recorder entries for tests to `tests` data logger.
* Tests use a larger text rendering limit
* Tests now purge the directory between examples. This prevents stray variables
  from influencing later tests.
* The handling of long UTF-8 sequences in tests was improved, which allows tests
  involving a lot of text (e.g. examples) to run faster.
