tworingtools 1.8.0

- rebuild-sims: Delete all simulators and recreate one for each compatible platform and device type pairing. - sync-forks: Make sure all your GitHub forks are clones into a given directory, and have “upstream” remotes pointing to the repos that were forked. - changetag: Extract changelog entries to write into git tag annotation messages. - prerelease-podspec: Branch and create/push a release candidate tag, modify the podspec to use that version tag, and try linting it. - release-podspec: Create a tag with the version and push it to repo origin, push podspec to CocoaPods trunk. - revert-failed-release-tag: In case `release-podspec` fails, make sure the tag it may have created/pushed is destroyed before trying to run it again after fixing, so it doesn't break due to the tag already existing the second time around. - bumpr: Increment the desired part of a version number (major/minor/patch/build) and write the change to a git commit.
