Improve devel project commands.

Let "osc develproject" (with new alias "dp") display the devel package
if it doesn't match the package name. Deprecate "--raw" option which
only was a crude workaround for that anyway.

Add "osc setdevelproject" (alias "sdp") command to change a package's
devel project / package.
