Reduce amount of imports needed

[Fristi]

A while back I gave presentation about refined and I stumbled on the fact that you need a few imports to get going:

For better ergonomics it would be great if we can reduce it

[fthomas]

import eu.timepit.refined.generic._
import eu.timepit.refined.char._
import eu.timepit.refined.boolean._
import eu.timepit.refined.collection._
import eu.timepit.refined.numeric._
import eu.timepit.refined.string._

can be replaced with import eu.timepit.refined.predicates.all._ and

import eu.timepit.refined.types.numeric._
import eu.timepit.refined.types.string._

can be replaced by import eu.timepit.refined.types.all._

Thanks, quite an improvement :)
