Editing Training Templates shouldn't update the base model

[dadmobile]

Or at least that's my personal opinion. :) I realize that changing this would require having a way to select a base model.

The reason this is annoying is that my standard flow for training is:

1. Create a template with default parameters
2. Run a test train
3. Run the new trained model to test it
4. Based on how step 3 goes, update the training template and go back to step 2

But right now you have to do an extra step between steps 3 and 4 to eject your newly trained model and open up your base model or else you can't edit the template (without accidentally doing training inception).
