Added a Python script for generating unique context ids for creating context sensitive help.

Browse Source 
The script requires Python 2.5. See comments at the head of the script
for more information.

This script generates a unique context id based for use in the QGIS
context sensitive help system. It uses the SHA1 hash for the class name
and converts the first 12 characters to a unique integer.
To create a context id, pass the name of the QGIS class on the command line.
Example:
./context_help_id.py QgsAbout
This script requires Python 2.5 or higher (hashlib was introduced at 2.5).
NOTE: Due to a change in the way context ids are generated, ids
generated by the old method (Java hashCode function) will be different than
the id generated by the new method for the same class.

# to decimal
