An update of git-cola to the latest upstream release, version 2.1.2.

Changes since version 2.0.8:

Usability, bells and whistles: * git dag now forwards all unknown arguments along to git log. https://github.com/git-cola/git-cola/issues/389 * Line-by-line interactive staging was made more robust. https://github.com/git-cola/git-cola/pull/399 * “Bookmarks” was renamed to “Favorites”. https://github.com/git-cola/git-cola/issues/392 * Untracked files are now displayed using a unique icon. https://github.com/git-cola/git-cola/pull/388 * A new “Find files” widget was added, and can be activated by using the Ctrl+t or t hotkeys. * A new git cola find sub-command was added for finding files. * git cola now remembers the text cursor’s position when staging interactively with the keyboard. This makes it easier to use the keyboard arrows to select and stage lines. * The completion widgets will now select the top completion item when Enter or Return are pressed. * You can now refresh using F5 in addition to the existing Ctrl+R hotkey. * Updated zh_TW translations. * git cola rebase now defaults to @{upstream}, and generally uses the same CLI syntax as git rebase. * The commit message editor now allows you to bypass commit hooks by selecting the “Bypass Commit Hooks” option. This is equivalent to passing the --no-verify option to git commit. https://github.com/git-cola/git-cola/issues/357 * We now prevent the “Delete Files” action from creating a dialog that does not fit on screen. https://github.com/git-cola/git-cola/issues/378 * git xbase learned to edit rebase instruction sheets that contain exec commands. * The diff colors are now configurable. cola.color.{text,add,remove,header} can now be set with 6-digit hexadecimal colors. See the git cola manual https://git-cola.readthedocs.org/en/latest/git-cola.html#configuration-variables for more details.

Fixes: * git dag was triggering a traceback on Fedora when parsing Git logs. https://bugzilla.redhat.com/show_bug.cgi?id=1181686 * Untracked files are now assumed to be utf-8 encoded. https://github.com/git-cola/git-cola/issues/401 * git cola now passes --no-abbrev-commit to git log to override having log.abbrevCommit = true set in .gitconfig. * git cola will now allow starting an interactive rebase with a dirty worktree when rebase.autostash is set. https://github.com/git-cola/git-cola/issues/360
