fix from_pretrained in_channels, etc.

[s-rog]

fix from_pretrained param in_channels
rename existing from_name to _from_name
added new from_name to match from_pretrained signature

[s-rog]

maybe should have pushed these to another fork... but these commits add dropout and drop_connect options as well as mish (as an option in set_swish)

[s-rog]

perhaps it's simpler to have just a from_name function and a pretrained boolean arg?

[ahmadmughees]

[s-rog]

you can use my fork for now

Good to hear! let me know if you think any of the changes I made are unintuitive since I did a little more than just fixing the channels issue
