* Added support for retrieve_index to Variables class
* Added default log level to Variables print methods
* Added default values to Python port
* Beginning feature-enable code for using Boost for threading instead of ACE
* Updated version to 1.2.8

* Removed ACE threading from UDP, Multicast, and Broadcast transport from Windows dlls and replaced with beginthreadex
* Python port can now launch threads for UDP, Multicast and Broadcast in Windows.
* Updated to version 1.2.9

* FEATURE: Added Python callbacks via define_function 
* FEATURE: Changed Knowledge_Record logical operators to return Madara::Knowledge_Record::Integer rather than Knowledge_Record (this allows for stl containers to work with Knowledge_Record more portably)
* Updated version to 1.2.10

* FEATURE: Added send, receive, and rebroadcast filters to the MADARA Python port
  * Properly acquires GIL to allow for calling Python methods from C++ engine
  * We do not currently have Aggregate_Filter support in the port, but I believe we will add this via slightly different method calls for the Python port.
    * The main issue with this right now (without a separate function call for adding aggregates) is that the ability to distinguish a python callable's arguments was taken out in Python 3.0 and readded later. To have a portable port, we can't really use the atrributes that were taken out for callable to work properly.
* Updated version to 1.2.11

git-svn-id: http://madara.googlecode.com/svn/trunk@1097 2850746a-f1c8-11dd-b507-8b4ecd5210be
* FEATURE: Python port now supports aggregate update filters
* FEATURE: Knowledge_Base now supports print alias for print_knowledge. Both will be supported, but print is more likely to be used since it is shorter and it also directly maps to print in Variables class.
* REVIEW: After code review, we have added const to more functions that should have the modifier on the functions, including print, get, and exists, neither of which should ever change the context.
* INSTALLER: A windows Nullsoft installer script was added for MADARA python
* Updated to version 1.3.0
