[BRLTTY] [PATCH] Use print function for Python 3 compatibility

[Hammer Attila]

Hy Joanie,

Help your work if I try testing this patch and Orca master branch with 
Ubuntu 13.04 daily live CD or a daily 13.04 build based installed target 
system?
Brltty side what package version I using for testing? In Ubuntu 13.04 
Brltty 4.4-5ubuntu5 package version are awailable. Good this package 
version for patch testing, or better use the testing with Brltty trunk 
release?

Orca master build related Python3 3.3 package version already awailable 
in 13.04, so master branch build I think will be work. Ubuntu level 
packaged gnome-orca version is 3.7.0.93-0ubuntu1.

Not promise you the test with tuesday or wednesday, but if 13.04 daily 
build possible using with Orca I try doing the testing before friday.

Attila
