Added the mimetype parameter for download url
The mimetype will be "application/x.moin.download", such that it will be moin specific.
There is currently some issue with firefox browser for the filenames with extension otherwise whatever mimetype we pass in url, the contenttype of the file being downloaded get set to that.
Posting changeset soon.

I think that is not a big issue. After you are done with that please work on a better layout of index for Filter, Upload and Download functions. Similiar to Download also delete and destroy could be implemented. rename in the meaning of move to makes also sense (move all selected items to an other level)
