moved build task to psake script files. but i'm not happy with the console output. next try is to use ps1 scripts with params
remove js which is not needed
tried another approach: use powershell scripts with parameters: even though psake is quite cool, i think this way is better. i like the feature in psake that you see how long actions took... i've to think about some simpler implementation to provide this information to the user. but focus now on a solution which isn't that pretty, but it works :) (&refactor it after)
