RFC: Disabling blinking cursor by default

[Matthew Garrett <mjg redhat com>]

The blinking cursor causes the processor and GPU to be woken up 
frequently. On one of my test systems, this causes somewhere in the 
region of 2 Watts of extra power consumption. I'd like to change the 
default for this to false. Anyone have any objections?
