Different initial selected value in <select>

[mbdavid]

Hi, first of all, thanks for this fantastic work.

I note that <select> has a different behavior when using template from DOM element than template string options on Vue initialization.

When use template from DOM element, Vue render select with no value selected (v-model = null).

When using template from a string options, Vue render select with first value selected (v-model = null too).

This is caused by some browsers' default behavior that whenever a <select> element is appended to a new parent, and its selectedIndex is -1, the browser resets it to 0. It seems Firefox is the only browser that persists the -1 value properly.

Ideally all browsers should persist the value, but I guess I can't change that so we can only add more ugly patches to Vue :(
