to jetbrains: downloads on served as text/plain

The downloads of jar files are served with a "text/plain" MIME type. This makes standard compliant browsers like Opera display the jar file instead of offering a download dialog.
Problem observed on: when trying to download the latest version (7.14) by simply clicking the download link.

Please fix this.

P.S.: the information about "text/plain" was taken by monitoring HTTP traffic with Fiddler, so Opera just interprets what's served.
