Bugfixes:

- SVG export text elements use generic font-family as backup, corrected item transformation issues
- Fixed RuntimeError caused when clearing item hierarchies from ViewBox
- Fixed example execution bug

Packaging maintenance:
- Added missing files to MANIFEST.in, fixed setup.py package detection
- Added debian control files for building source packages
- Fixed version numbering in doc, __init__.py

+Description: Scientific Graphics and GUI Library for Python
+ PyQtGraph is a pure-python graphics and GUI library built on PyQt4 and numpy. 
+ It is intended for use in mathematics / scientific / engineering applications. 
+ Despite being written entirely in python, the library is very fast due to its 
+ heavy leverage of numpy for number crunching and Qt's GraphicsView framework 
+ for fast display.
