uiFramework fails to start on windows

[BigFunger]

Seems to have been introduced in https://github.com/elastic/kibana/pull/9803.

Output from console

> kibana@5.3.0 uiFramework:start C:\code\kibana
> grunt uiFramework:start

potential fix: https://github.com/elastic/kibana/blob/master/tasks/ui_framework.js#L16

changing:

cmd: /^win/.test(platform) ? '.\\node_modules\\.bin\\webpack-dev-server' : './node_modules/.bin/webpack-dev-server',

to

cmd: /^win/.test(platform) ? '.\\node_modules\\.bin\\webpack-dev-server.cmd' : './node_modules/.bin/webpack-dev-server',

made it work on my system.
