need help in two issues:
1. use better icon - I just reused the Filter icon
2. lines of merge commits are still rendered - need to skip them since they don't link to any commit when filter enabled. I didn't manage to solve by my own right now
Using issue tracker instead of built-in supported commit web link is based on the following reasons
* repo may have multiple remotes
* it is not good to open an context menu to choose which web to visit with multiple remotes
* some remote servers are not supported by this app
* start background task only it is needed
* solve the problem that we can not use `ViewModels.Preference.Instance` until resource ready
* remove avatar sever settings
* add missing translations and it's no need to add `OnPull` suffix since it already has a prefix `Text.Pull.`
* when enable fetching all branches of selected remote, use merge/rebase command instead of pull
* re-arrange orders of options in pull popup panel
* default enable `Fetch all branches`
* tooltip for swap button
* move `Views.CompareTargetWorktree` to `Models.CompareTargetWorktree`
* remove unused `Models.IObjectId`
* fix swap not working when target is Worktree, because Commands.CompareRevisions's Args do not changed after swapping
* `--rebase-todo-editor` launches this app as a git `sequence.editor`
* `--rebase-message-editor` launches this app as a git `core.editor` which runs on background by reading rebasing jobs
* `--core-editor` launches this app as a git `core.editor`
* `--askpass` launches this app as a SSH askpass program
* add a new context menu to push local LFS object to selected remote
* supports to choose remote for fetch/pull/push/lock/unlock actions
* auto select remote if there's only one remote
* Only allow to start interactive rebase from merged commit in current branch
* The order of commits in the interactive rebase window is as same as it's in histories page.
* Unlike anthor git frontend app `Fork`, you should edit the final message on the last commit rather than the previous commit that will be meld into while squashing commits
* replace icon with common whitespace icon in other editors
* button tooltip translations
* rename `_showHiddenSymbols` to `_showHiddenSymbolsInDiffView` to make its usage clear
* change the order of this button
