Release 0.4.7: Numerical solver and integration
eb553d7 
New features
- `root` for numerical root finding (#36)
- `integrate` for numerical integration (#42), using Romberg algorithm
- Auto-simplification of `i*i` as -1 (#411)

Bug fixes:
- `LastArg` and `Undo` were not correct after comparisons (#402)
- Invalid equation created for symbolic comparisions, e.g `A=B` (#403)
- Converting `100!` to a based number would display `#00` (#405)
- Avoid crash if running out of memory processing fractions
- Possible memory corruption during negation of complex numbers (#406)
- Fix typo in `User` settings menu, rename it as `UI`
- `->Q` could give incorrect result for decimal32 and decimal64 (#409, #410)

Enhancements:
- Accelerated editor when `VariablesMenu` is shown (#404)
- Being able to pass equations containing equal sign to solver (e.g. `X+1=3`)
- Insert a single colon `:` inside text
- Sharing more code between plotter, solver and integrator
- Simulator uses the DB48X keyboard by default
- Label for constants menu changed to `CNST`
