用 itermocli 定制 iTerm 窗口布局

[itermocli](https://github.com/TomAnthony/itermocil)

玩法很简单，放个 YAML 配置到 ~/.termocli/dev.yml。比如：

windows:
  - name: dev
    layout: main-vertical
    root: ~/workspace/p01
    panes:
        - commands:
            - git fetch --all
          focus: true
        - eval "$(docker-machine env dev)"; ~/workspace/env/dev/bin/python p01-watcher.py
        - eval "$(docker-machine env dev)"; docker logs -f p01_app_1

这样就能整出如下布局：

.------------------.------------------.
| (0)              | (1)              |
|                  |                  |
|                  |                  |
|                  |                  |
|                  |------------------|
|                  | (2)              |
|                  |                  |
|                  |                  |
|                  |                  |
'------------------'------------------'
