new features
- add `--preserve-path` option to `gita clone` command so that repos will be cloned to the preset paths
- add `gita flags` sub-command which sets per-repo custom git flags
- support bare repos
- allow shell mode commands to be defined in `~/.config/gita/cmds.yml`
refactoring
- replace `~/.config/gita/groups.yml` config file by `~/.config/gita/groups.csv`. To upgrade, user needs to change the file name and also the content. For example,
home: [blog, dotfiles, gita, resume]
changes to
home:blog dotfiles gita resume
bug fixes
- disallow renaming into an existing repo name
