Work-around for Safari 6.0.X JIT issue discovered by @artiomchi
Adding the build of bit2factor.org from git commit 1825396c333f95422c16a60ce560022ac111449f.
1825396c333f95422c16a60ce560022ac111449f is the last version before the Safari JIT bug was discovered, so it doesn't have the work-around in place.
Expose BIP38 test suite to users
Put up compatibility notice on site
Close #2 as there isn't much else we (the javascript BIP38 sites) can do… :/
