Errors in Python Catalog: items are not always in alphabetical order

[mobluse]

Describe the bug
In the Catalog the items are not always in alphabetical order, e.g. battery() comes after keydown(k) and before ldexp(x,i). There are other such sorting errors.

To Reproduce
Steps to reproduce the behavior:

1. Click Home
2. Choose Python
3. Choose Python shell
4. Click Toolbox
5. Scroll down to Catalog
6. Click Right
7. Scroll down to keydown(k)
8. See that battery() comes after keydown(k)
9. Also see that battery_level() and battery_ischarging() are missing from Catalog.
10. Also forward(x) and fmod(a,b) are in the wrong order.

Expected behavior
The list in Catalog should be sorted in alphabetical order like in Numworks and should contain
all functions, except maybe functions from some selected modules.
