v0.5.0

Added

• submit: Add spice.submit.publish configuration to allow making --no-publish the default. Use this to work with unsupported Git hosting services.
• branch checkout: Add spice.branchCheckout.showUntracked configuration to always show untracked branches in checkout prompt.
• branch create: Add --[no-]commit flag and accompanying spice.branchCreate.commit configuration to create stacked branches without committing changes.
• submit: When importing existing CRs, also detect existing stack navigation comments and update them instead of posting duplicates. This will only work for comments posted git-spice v0.5 or newer.

Fixed

• submit: When submitting with --no-publish, don't fail if the repository is hosted in an unsupported Git hosting services.
• {branch, upstack} onto: Always rebase commits after the operation--even if the branch's base already matches the target. This better matches user expectations when the branch and base diverge.
