No local cursor by default due to issues #27, #29.

In Safari, local cursor rendering is corrupt. In firefox 3.6.10, local
cursor rendering causes a segfault. Probable that the .cur format is
not 100% compliant (even though it works in Chrome and firefox 3.5 and
firefox 4.0). So just disable it by default until I can figure out how
to address the problems.
