TI-Basic "debugging"

[adriweb]

We have quite a few information already (and are able to retrieve some more from some known memory locations) in order to have an idea of the current execution state of a TI-basic program.

With this information, we should be able to make some kind of "debugger", or at least a live-viewer of what's going on:

• current program being run (basic_prog)
• current line (curPC)
• current variables (we have that already with the var list/viewer)

The variable viewer as of now can already show (and reformat, but I guess we can't use that feature here, unless we have original line info...?)

This "TI-Basic" debugger will likely require a new dedicated dock in order to maximize its usefulness and UX, with a custom UI being split in 2 parts:

• a code viewer (like the current one, with syntax highlight, line numbers etc.)
  • highlighting the currently executing line (and fetched parts)
  • ability to stop and step
• a variable viewer -> later on, see TI-Basic debugging enhancements #456

I'll add that to the "v2.0 - source-level debugging" release target, as it seems quite appropriate, but I guess we'll see over time how it develops.

( Dev to be done in a feature/basic-dbg branch )

I want a label tracker

todo: think how/if #287 can help with TI-Basic debugging.

Added a few ideas in the "code viewer" part.

Splitting this so that current working stuff can be merged into master, and creating another issues for the rest/improvements to be done later.
