Release 0.7.13 "Murderers" - Solver improvements

This releases focuses on improvements to the solver, with the completion of the Columns and Beams section from the HP50G equation library.

Features

• equations: Add remaining equations from "Columns and Beams"
• loops: For loops on lists and arrays
• menus: Add R→D, D→R, →Polar and →Rectangular
• menus: Automatically select tools menu for library equations
• units: Allow ubase to work on expressions
• units: Graphic rendering of units

Bug fixes

• 48calc.org: Fix mouse click position
• #ABC #DEF - now correctly produces a based number with >64-bit wordsize
• conditionals: Parse and evaluate IFTE correctly
• equations: Fix Elastic Buckling
• files: Avoid crash in file_closer if file was not open
• istack: Enable Swap feature on top two levels
• menu: Update SolvingMenu when updating VariablesMenu
• parser: Deal with negation more "normally", parse -a² correctly
• solver: Compute units correctly for inputs
• solver: Do not change unit when storing in a solver variable
• solver: Emit correct error message in EvalEq if missing variables
• solver: Preserve errors reported by underlying function
• units: Do not evaluate/render units with names
• units: No longer read variables m and s while processing 1_m/s
• units: Simplify units that convert to real numbers

Improvements

• Update .gitignore
• build: Add BMP files to the distribution
• complex: Optimize exit conditions for parentheses
• solver: Add test for equation library
• solver: Add tests for solving with units
• solver: Improve behaviour of EvalEq
• solver: Keep units and constants as-is in equation
• solver: Make precision relative to equation sides magnitude
• stack: Show vectors vertically by default
• ui: Do not persistently hide stack with current equation
• units: Keep power integral, i.e. avoid getting 1_m^2.0/s
• units: Strip tags from unit conversion functions
• units: The EvalEq command should not evaluate dates
• wasm: Add logos to the repository
