Vue.js 0.12.10 发布轻量级 JavaScript 库

Vue.js 0.12.10 发布，此版本更新内容如下：

Support one static <option> inside <select> with v-model + dynamic options:
```
<select v-model="selectedUser" options="users">
  <option value="">Select a user...</option>
</select>
```
This static option will be selected by default if the v-model value is falsy (excluding 0). Options created from users will be appended after the default option.
Dynamic component wait-for listeners are now attached in the component’s createdhook, thus firing the event synchronously in compiled hook will now properly trigger the DOM insertion.

template parser now trims empty textNodes from <script> templates, avoiding unnecessarily turning components into fragment mode.
#1109 mustach tags inside <textarea> are interpolated only once
#1116 transition hangs when immediately leaving after entering
#1117 synchronously calling done in leave transition hook causes error
#1118 nested <template> not rendering in Safari
#1119 out-in transition mode not working as desired when switching faster than transition duration.
#1124 number attribute param for v-model not respected on <input type="radio">.
