Removed unnecessarily tracked files.

Removed build generated files, binaries and editor backup files,
Makefile.Debugs and Makefile.Releases, object_script files and generated libs.
Spared Windows .exe until a new version is released.
Timer with 10 sec interval in layline calculation thread
route data to calculate laylines by signalling, no calculation on empty route data
Fixed calclulatelaylines.cpp not building because of missing member variable.

Removed calculateComplete() slot because it is not used anywhere.
Fixed QVector ASSERT failure "index out of range" in boat.cpp.

The ASSERT was triggered only in debug mode, although the code always
tried to access the 0 index of a QVector. Even when the vector size
was 0.
Fix for QVector ASSERT index out of range in calculatelaylines.cpp.

CalculateLaylines::getNextPoint() seemed to return garbage in release builds.
Removed unused code from loadObstacles.

There were for-loops that whent though every point in every chart item
and those points were appended to a list that was only used in a commented-out
debug code. Those for-loops slowed down the application start-up time significantly.

Also cleaned-up LoadObstacles code a bit.
Initial windows build overhaul
Merge branch 'spring_2013' of https://github.com/UpWind/devel into spring_2013
Fix libpq-fe.h not found in loadObstacles.h.

Compilation failed when loadObstacles was accessed through UWCore.
As a fix added include paths for postgresql and gdal to UWCore.pro

This is a temporary fix. At some point we should really fix the .pro files.
Initial implementation of pixel perfect chart symbols. Adds symbols for
different rock types and left and right buoys.

Created data structure that contains the type of the
point object received from the database. Extended ChartObjectInterface
and classed Rock and NavaId to support the data structure.

Disabled QGraphicsItem's cache mode in ChartWidget. When chart item size grow
over a certain limit the caching behavior became slower than drawing the
item again using the item's paint method. Disabling caching results that
the chart item is re-drawn constantly, but the performance stays constant with
every zoom level. More elaborate means to handle the caching is needed
if better performance is required at later date.
Smallish fix to repair windows build of missing function implementations.
OpenGL mode activated with SampleBuffers(AntiAliased). Cachesize extended to 300Mb to fix caching failures.
Plethora of changes to datanmeasimulator, ui, and instruments.. some are still incomplete.

Effectively changes datanmeasimulator to one that actually holds an
internal state of the boat instruments and enables an instrumentplugin
to change those according to the interface. In short, you get to drive
the boat as a real sailor. Other changes are to ui and stuff.
Added required map symbols and logic.
Changed compass instrument to show the heading, doubt this will be the end of the story.
Forced cartesian to [0,360] angle and fixed some pointer semantic.
Merge branch 'spring_2013' of https://github.com/UpWind/devel into spring_2013
Changed zooming
Added VelocityHandle instrument and changed datasimulator.
