[Elecraft] CW rise time

[Leigh L. Klotz, Jr WA5ZNU]

According to http://www.elecraft.com/K3/k3_app_notes.htm this change was 
phased in "Approximately Jan 20, 2008 Approx. s/n 211."  So that sounds 
to me like the current shipping ones are 5ms instead of 8ms.  It also 
alludes to future firmware control enabled by the mod.
