Bugfixes on the merge_model GUI (#2697)

Browse Source 
This fixes a few cosmetic bugs in the merge models console GUI:

1) Fix the minimum and maximum ranges on alpha. Was 0.05 to 0.95. Now
0.01 to 0.99.
2) Don't show the 'add_difference' interpolation method when 2 models
selected, or the other three methods when three models selected

alpha - The interpolation parameter. Ranges from 0 to 1. It affects the ratio in which the checkpoints are merged. A 0.8 alpha
would mean that the first model checkpoints would affect the final result far less than an alpha of 0.2
interp - The interpolation method to use for the merging. Supports "sigmoid", "inv_sigmoid", "add_difference" and None.
Passing None uses the default interpolation which is weighted sum interpolation. For merging three checkpoints, only "add_difference" is supported.
interp - The interpolation method to use for the merging. Supports "weighted_average", "sigmoid", "inv_sigmoid", "add_difference" and None.
Passing None uses the default interpolation which is weighted sum interpolation. For merging three checkpoints, only "add_difference" is supported. Add_difference is A+(B-C).
force - Whether to ignore mismatch in model_config.json for the current models. Defaults to False.
