The mechanism for updating the `VariablesMenu` was too aggressive. It updated the whole series of menus after every single key. The same thing was true with the catalog. Change to a mechanism where updates are only made when necessary. For example, the `VariablesMenu` only updates when a `Sto` or similar operation changes the content of the directory.

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` Signed-off-by: Christophe de Dinechin <christophe@dinechin.org>

When the
VariablesMenuis active, the text editor becomes very sluggish on DM42.Observed with the
Democontent while on battery power.The text editor is quite responsive even with multi-line content when another menu of similar complexity is active, including menus with animations. For example, the
Dispmenu still has an animation on theCommandmenu entry when the long command is selected, but even with that menu active, the editor remains snappy.Possible cause (to be investigated): scanning through the object list is expensive because it has to go deep? Seems unlikely since the representation of program objects makes it relatively easy to skip over them.
Other possible cause: all menu items being animated?
