extend build process

[seebi]

on develop we want:

• data-pull on runtime to have current staging graph on staging page
• commit pulled data to develop
• use client credential secret
• trigger is repository change AND
• time-based

on master we want:

• no data-pull
• use data from repository

It is nearly done, but my grep expression is not accepted by make.
@seebi do you have any idea?

It complains about the caret ^

git status --porcelain | grep '^[MTD] '
make: *** [Makefile:31: git-commit-and-push] Error 1

maybe this? ^^
