[IMP] web: add simple calculator on numeric fields

Add a new behavior to numeric fields, possibility to enter value manually or to use a simple arithmetic expression that will be evaluated.
Example: =20+3*2
In order for the computation of the arithmetic expression to be done, the value needs to starts with = and then an expression can be entered. We only support the basics mathematical operations + - * / ( ) ^
User locale and digits separator are taken into account. If the value entered can't be evaluated to a numeric, the field will be displayed in error.
