[Bioperl-l] translate() again

[Heikki Lehvaslaiho]

Further prompting from Amir got me to reorganize and clean the new
translation code in CodonTable.pm for easier reading and
maintainability.

As a side effect, overall performace increased again a bit (25-50%). 
The speedup is most notable in short sequencences which were not doing
so well last time. The total speedup from 0.7 translation code is now
6-10x.
