ui-snapshot: add dwimmery

When downloading a snapshot, the snapshot name will often contain the repo
name combined with a tag. This patch tries to exploit this so that the
correct revision is downloaded even if no specific revision is specified.

PS: this only occurs if neither 'h' nor 'id' is specified in the query-
string.

PPS: this also fixes a bug which occurs when trying to download a filename
with an unsupported suffix: it used to try to print an error message to
the user but failed since it didn't prepare the output properly.
