[Bf-committers] Numeric fields should accept coma and convert it todot

[Campbell Barton]

recommend to look at interface.c and bpy_interface.c -
BPY_button_exec(), in principle what you suggest could work however
all parsing is done by python its not so simple to make decisions
based on input unless we write our own.

In brief it works like this:
* user inputs some number/py-code/units
* for unit buttons blender does python compatible replacements (yes,
units systems cheats by relying on python :-) ).
* python evaluates this string - if its a tuple ist sum'd, otherwise a
number is expected.

The conflict with units is input from multiple units system is
possible, so you can type in 10cm even if Imperial units are selected.
Or 10' when Metric is used.
