Additional pull and push options

[JetpackDuba]

Sometime the default pull and push options may not be enough for the user. Some interesting options to be considered are:

• Push

  • Force push with lease (perhaps should be the default already?)
  • An alternative way to push to a specific branch rather than using the context menu (check this comment for more info)
  • Option to create a new remote branch with a different name instead of pushing to an existing one.

• Pull

  1. Pulling from specific branch without using the context menu (same as with push).
  2. Pull with rebase combined with previous point.

Feel free to suggest additional requirements for such feature.

please don't make Force push with lease the default. should be a conscious decision :)

@adam-ce it's already with lease by default, I should update this issue. However, you can disable this behavior in the settings if you wish.
