Cura plugin: ZToolChangePattern

Plugin to use with Cura. More information on http://wiki.ultimaker.com/Category:CuraPlugin
I test it with Cura 12.12A
Lets use a simple STL to obtain results in several colors (supports up to 3 extruders). It is not necessary to create a solid for each color and allows coloring quickly any existing design.
The basic setup only requires to indicate the tool change interval or specify a list of comma separated values of heights(mm) that change will occur. If the object is higher than the last value programmed(or empty list) cyclic repetition by steps specified in the first parameter.
The other parameters are for fine adjustment of retractions and different filaments diameters.
