Implements a more flexible internal connect function for standard nodes (compositor, shader, texture). Allow feasible datatype connections by priority. The priorities for common datatypes in compositor, shader and texture nodes are encoded in a simple function. Certain impossible connections (e.g. color -> cycles shader) are excluded by giving them -1 priority. Priority overrides link status: If a higher priority input can be found, this will be used regardless of link status. Link status only comes into play for inputs with same priority.
