Slake overhaul

[gkz]

• add join
• watch checks for new files/deleted ones
• only build if file has changed
• some sort of nice DSL to write them

Any DSL suggestion ?

With an array

task \build ->
 build do
   directory: 'src/'
   out: 'lib/'
   prepend-files:
     * 'vendor/prelude.js'
     * 'vendor/foobar.ls'
   out-file: 'lib.js'

DSL-like ?

task \build ->
  build ->
    @prepend-file 'vendor/prelude-ls'
    @directories.push 'src/'
    @output-directory = 'lib'
    @output-to = 'lib.js'

But this depends "how far are we going". I think we can all agree that compiling some files, running tests etc are something common to (almost) every project
