Release 0.8.3 "Blindness" - User mode and custom header

[c3d]

This release focuses on various user interface aspects.

Features

• User mode, key assignment, ASN, STOKEYS, RCLKEYS, DELKEYS. Unlike HP calculators, key assignments are per directory, with inner directories inheriting the key assignments from the enclosing directories.
• Add Header command to customize the header. For example, you can now show the path in the header, or any relevant information. This customization can be done per-directory.
• Implement Menu, TMenu and RclMenu commands
• help: Automatically create links for references to RPL words. When we have sin in the Markdown file, the calculator will
  automatically insert a hyperlink to the corresponding entry. Note that this only applies to the calculator, not to the GitHub rendering of the Markdown files.
• Display object type in the Info box of the interactive stack.
• Fallback graphic rendering of objects to text when the usual heuristics did not allow the graphics to fit in the alloted pixel space. For example, a fraction that does not fit will now display using the textual form if that particular form can fit in the given box.

Bug fixes

• Fix a bug that could cause the text editor cursor to move past the end of the editor when inserting text, possibly causing memory corruption.
• The Show command will now show all digits, and render fractions using multiple lines for the numerator and denominator so as to be
  able to show more digits in a readable way.
• When terminating a command using auto-completion in the Catalog feature, the command that was entered is now present in the
  command-line history.
• Arithmetic operations that combine text or lists and unit objects now behave correctly. For example, adding a unit to a list appends
  like any other object.
• Move updir if evaluating an updir directory, instead of corrupting the directory stack.
• Clear transient object if entering the interactive stack, e.g. when exploring the interactive stack while in the SolvingMenu and solving an equation, and correctly update the transient object when switching menus.
• Render vectors as RPL code in the equation examples.
• Correctly redraw the text editor when using the interactive stack Echo feature with stack items spanning multiple lines
• Fix minor typos in the equations documentation.

Improvements

• tests: Only evaluate after parsing RPL examples in the documentation when the stack is not empty
• The Wait command now returns a key code in the same style as HP calculators, i.e. with row, column and plane. Also, like HP calculators, it processes shift keys and returns a plane, instead of returning the keycode of the shift key.
• Capitalize Path, CrDir, Home, UpDir so that their rendering in compatibility mode with the Cmd setting looks better.
• Add DB48X_SPEEDUP environment variable support in the simulator.
• documentation: Update Authors section
