Some speed values were set to zero accientally,
these updates ensure that all speed params have
non zero values.
Also, I noticed some temperatures were not correct.
I added a few changes to correct layer_0, initial,
and final print temperature values.
The default print temp is still not correct, I will
submit another commit for this.

Add definition for Replicator+, along
with three extruders: SE+, SE+ Tough,
and SE+ Experimental.
Add Replicator+ settings for PLA & TPLA.
These are similar to Method settings,
with some first layer adjustments.
