emc_task_plan_init

Jon mentioned he was having a problem with consistently using coordinate
systems under tkemc. I'm wondering if recent changes in the way
initialization is done is contributing to these confusing results.

There are times when the g-codes displayed by tkemc do not seem to match
the internal state of the machine.

I found this example while writing a backplotter.

mdi => g43 h1
relative display shows tool length offset distance

reset => emc_task_plan_init
g code display changes to g49
relative display still shows tool length offset distance 

mdi => g49
relative display returns to no offset
g code display still shows g49

a similar thing happens with feedrate display vs actual feedrate, and the
same problems show up with the current xemc.
