1) svg related

Removed deprecated references to qgssvgcache
Some additional small changes to src/core/qgsmarkercatalogue to support svg from directly in the catalog
Added static method too src/core/qgsmarkercatalogue to retrun a pixmap of svg given a filename and a scale factor

2) Vector props
Removed unimplemented collision detection option on vetor label properties dialog and signal slot setup for 
that option in lable subclass
