svg exporter updates
SVG export looks good.
SVG export fixes

updated versioning system
Fixed doc version (again)
Added debian control files
Removed incorrect version numbers
merged with acq4
SVG export fixes:
  - unicode support for text objects
  - always export in scene coordinates with offset from root item
Bugfixes:
- Fixed RuntimeError when clearing items from ViewBox
- SVG exporter adds generic font-family names to text items
Added deprecation warning for Node.__getattr__
Expanded flowchart.Node docstrings
Added custom node example
Updated flowchart documentation
Speed up PlotCurveItem in some cases (avoid drawing shadow when it is not needed)
Actually added flowchart documentation this time.
Performance improvements:
  - AxisItem shows 2 tick levels instead of 3
  - Lots of boundingRect and dataBounds caching
    (improves ViewBox auto-range performance, especially with multiple plots)
  - GraphicsScene avoids testing for hover intersections with non-hoverable items
    (much less slowdown when moving mouse over plots)
These are deep changes; need good testing before we release them.
Improved performance for remote plotting:
  - reduced cost of transferring arrays between processes (pickle is too slow)
  - avoid unnecessary synchronous calls

Added RemoteSpeedTest example
Fixes against previous commits:
 - fixed example testing script
 - Added finer axis ticks back in some instances
 - fixed improper bounds caching in log/fft mode
 - fixed exception handling in remoteproxy
