Various fixes [read below]

[fterrier]

Hi @arosequist,
Thanks for the great library, I use it and it seems to work quite well.

Here's a pull request with a few proposals on things that can be improved:

• I fixed a problem where the "Loading" was only displayed for a flicker and then gone, it now works properly
• Also fixed an issue with an empty
  being visible at some point, it was pushing the content down a few pixels so I've set that to "display: none;"
  • I've refactored the way the channels are created and killed in order to fix some potential race conditions. I'm not sure about that one perhaps you want to have a good second look?
  • I've added a IWilUnmount that closes all the channels
  • I've merged @robili's branch as well

  Let me know what you think,
  Franz

Hi @arosequist, @swannodette,

I've added a few commits to the PR and changed the module quite a lot:

• I have fixed the issue with the dropdown disappearing before a selection could be made
• I have made the module a little less customizable but a little easier to use, by providing sensible defaults and a "bootstrap wrapper" that just adds the correct classes to the elements. I have fixed your example so they still work and they need a little less code to work so I guess that's a step in the right direction? Let me know what you think.
• I have also added a few "features" that I needed, such as the ability to provide your onKeyDown handler and a input-focus-ch that is used to set the focus on the input field from the outside (that one does not really work well on iPads and other tablets yet.)
