Subject: [PATCH] Add a watch option

Similar to the way psc-ide support works, the purs-loader now tolerates
compiler errors when the `watch` option is true. When webpack is being
run in watch mode the user can set `watch` to true in order to avoid
failing the webpack bundle creation when the PureScript compiler fails.
