Release 0.4.7: Numerical solver and integration

[c3d]

New features

• root for numerical root finding (Numerical solver #36)
• integrate for numerical integration (Numerical integration #42), using Romberg algorithm
• Auto-simplification of i*i as -1 (Auto-simplify expressions containing i #411)

Bug fixes:

• LastArg and Undo were not correct after comparisons (Comparisons do not set last arguments #402)
• Invalid equation created for symbolic comparisions, e.g A=B (Evaluating B=2 results in Internal object. #403)
• Converting 100! to a based number would display #00 (The Cycle key displays 100! as #00 #405)
• Avoid crash if running out of memory processing fractions
• Possible memory corruption during negation of complex numbers (Invalid object for some complex negation operations #406)
• Fix typo in User settings menu, rename it as UI
• ->Q could give incorrect result for decimal32 and decimal64 (->Q gives wrong result for 0.84375 #409, decimal_to_fraction should deal with complex numbers #410)

Enhancements:

• Accelerated editor when VariablesMenu is shown (The VariablesMenu is too slow #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
