less console output
+getSpeed, +attach.

In the script, a polyora target now supports the getSpeed method that returns
the speed of a point given in object coordinates.

Polyora targets also support the 'attach' method that allows attaching a point
to a polyora object.
State machine.

Added a state machine to scenegraph.js
Created an example to show how to use it.
track3d: basic 3d

very basic 3d. Now compiles. Untested.
Done in the train St Malo -> Zurich.
removed FindOpenMP.cmake
fixed orientation
solved conflict

Conflicts:

	data/visual.db
Rejects false positives.

To limit false positives, degenerated false positives are rejected.
The minimum number of matched features to decide a positive has been reduced
from 15 to 10.
cross compiles with mingw.
Merge branch 'cross'
Decreases false positives.

Restriction on homographies are more strict. Min num matches 10 -> 12.
Homography refactoring

The SPolyoraTarget now has a homography() method that saves the homography to another object.
This is useful in scripting, to save the current transform for later use.
