dx improvements

A list of improvements that could improve the developer experience:

CLI:

• if no commands/args given, look for bs-config.js in local dir, so that browser-sync will work as expected for users that have previously created a config using browser-sync init 2bf65b8

• if no commands/args given and the current directory has no bs-config file, start in server mode with some sane defaults.

• allow multiple configs to be given on CLI and merge into 1. This will allow a 'base' configuration and then can be overriden by passing multiple paths, eg:

  browser-sync conf1.js conf2.js

  where conf1.js contains a full config, but then conf2.js can override anything in the first

• if no commands given, but instead something that looks like a URL, automatically jump into proxy mode, eg:

  browser-sync https://example.com 

  Would just do what you'd expect and start a proxy for that address

Any more from the community, would be glad to hear suggestions :)

All excellent points!

What would "sane defaults" be for 2? Start server in current folder and watch 2 levels of files excluding some commonly excluded folders? (Node_modules, etc)
