Missing # in acessor sourceId causes Error when importing, previously exported Collada, with assimpnet

[Solaer1]

A Missing # in the source id of the accessor in library_geometries/geometry/mesh/<All sources(Position, Normals, texcoords etc)>/technique_common/acessor.source, causes an "Unknown reference format in url" error, when importing with assimpnet. Blender does not seem to be affected. An easy fix would be to change the lines 139, 157, 173 in SouceGenerator.cs to: Source = "#" + source.Float_Array.ID,. Seeing as the # is present in other urls, this is likely an oversight.
