elias.bachaalany ac5d88a83b IDAPython 1.4.3: 
- IDA 6.0 support
- Python CLI now prints expression evaluation result (no need to use print())
- Changed Alt-8 to Ctrl-F3 (because it conflicts with window switching key Alt+n)
- Added get_highlighted_identifier()
- Added PluginForm class to allow UI development with either PyQt4 or PySide
- Added idautils.Entries() to enumerate entrypoints
- idc / AddConst() was broken
- Minor fixes

Registers multiple data types and formats at once.
To register one type/format at a time use register_custom_data_type/register_custom_data_format
It employs a special table of types and formats described below:
The 'formats' is a list of tuples. If a tuple has one element then it is the format to be registered with dtid=0
If the tuple has more than one element, then tuple[0] is the data type and tuple[1:] are the data formats. For example:
many_formats = [
(pascal_data_type(), pascal_data_format()),
(simplevm_data_type(), simplevm_data_format()),
(makedword_data_format(),),
(simplevm_data_format(),)

The first two tuples describe data types and their associated formats.
The last two tuples describe two data formats to be used with built-in data types.
