#85 Issues with making channels

I just made the `@FastLBRY:f` official LBRY channel for FastLBRY. And there was a few issues with the creation process. - It gave an error with not allowing integer bids. I tried to bid `10` at first. And it returned an error. Then I changed the bid to `10.0` and it worked. This could be done automatically. - There is no support for quick inputs like in `publish`. In there I could do `bid 10` in the single line to update the bid. Here I need to type `bid`, press enter and only then type `10.0`. - Do not upload images as I update the settings, but upload them as I type create / publish. The idea is that I could be not sure about my thumbnail choice, and already start configuring things. I do not want million images uploaded. Only one. The final. - Missing save / load presets. I might want to save the preset before I press create, so if some error happens, I will not need to re-set everything from scratch.
