fanquake ced7f77df5 Update default URL in verify.sh
The current default URL doesn't seem to exist.

Unsure wether this should be updated to point to 0.7.2 now or wether
just to wait untill 0.8.0 is out and point there?

Commit also fixes a minor typo in the macdeploy notes.txt

### This script attempts to download the signature file SHA256SUMS.asc from SourceForge
### It first checks if the signature passes, and then downloads the files specified in
### the file, and checks if the hashes of these files match those that are specified
### in the signature file.
### The script returns 0 if everything passes the checks. It returns 1 if either the
### signature check or the hash check doesn't pass. If an error occurs the return value is 2
