first version of build step for assets
add component settings to build
add component events to build
add trl cache to build

the second level in memory didn't change
don't check for db in build, build should be independent of db
only build packages
ccw for component settings in build
create build folders automatically
if we don't have a db configured yet skip kwc resources

required to be able to build assets without db
add build folder to gitignore
cc: check build for up to date git revision
fix ccw for assets
allow lazy building, required for tests
improve build version check
move sass imports to correct folders to match their import name

for some reasons phpsass magically was fine with this
use libsass/sassc for compiling scss
add susy and compass-mixins as individual libraries

previously they where contained in phpsass
don't use stylesheet-url, doesn't work with libsass
remove phpsass
allow detecting of all possible languages statically

this makes it possible to build without database
