tmp commit: mock on IO constructor worked
fetching projects and assets from local folder works

- pass project root path from node context to phantom js context via cookie
- mock on IOclass
  - constructor: load project json and assets from local directory
  - soundRequest (atm: sounds are not being fetched)
tmp commit: project fetcher added. not working yet
project fetcher implemented
passing project base path to IO Mock improved

- former: stored as cookie
- now: variable stored in global object (window)
rewrote project fetcher

- use pipe instead of buffers when fetching / storing results
- instead of disabling gzip via http header, use zlib api to decrompress in case of compression
Merge branch 'project-fetcher'
