Merging in the runtime -> environment transition work. The merge was janky AF. I have little faith.

Backspacing behind X index 0 backs up to the previous line as it should

User backspace visually deletes the character behind the cursor and moves the cursor backward

User input is echoed to the screen as they type it - backspace and arrow keys not supported yet

The user input is now being collected through a combination of SDL keyup and textinput events

The last line is staying empty because now I'm artificially constraining the maximum number of character lines on the screen

Scrolling works properly but the bottom line is not staying empty

Scrolling was working then it got busted but basicruntime_graphics.go hadn't been committed yet so I don't know what I broke

All output is going to the SDL window and the cursor is automatically advancing then stopping at the bottom row, but the window doesn't scroll yet

Add DELETE command to delete lines in the program (the syntax is kinda confusing and doesn't fully match up w/ the basic spec - easy to delete the entire program)

Add MOD() for modulus operations. Only works on integers.

Introduced a bug with the BasicVariable transition wherein any modification of a variable's value that should result in the construction of a new value actually modifies the variable's stored value. Example:

All tests passing. New tests added for MID() function and multi-dimensional array operations.

Fixed argumentList() parsing to produce a unique type of leaf that identifies and differentiates function argument lists from variable array subscripts

The recent dimensioned variables changes broke the way that user function arguments are parsed. Consider this debug session on the tests/functions.bas file:

DIM A#(3) is working correctly, just need to fix assignments

WIP : Dimensioning is setup but not working, assignments always go to index 0 regardless of dimensions, see tests/ararys.bas

BASIC is compiling again. BasicVariable is in place everywhere BasicValue had previously been used to hold variables. Still bugs.
