[galaxy-dev] [Patch] enhance the toolshed upload error checking

Hi all! If you upload a tool with a tool_dependencies.xml file that does not fit the <requirement> informations in the wrapper the developer will not be informed about that error. Furthermore, the repository are updated and the only hint a developer get is an empty or missing dependency field in the toolshed. In my opinion the developer should be informed that the specified informations are wrong or insufficient and the upload should be aborted. "Talk is cheap. Show me the code." - please see the attached patch. Regards, Björn
