Set time on make (#35)

* Time can get set from makefile

* Added setting make time into simulator

* Added  Hash in settings

* Added default location

* Cuts the Githash to 6 characters in the settings in case the makefile didn't do that already

* bump gossamer commit

* remove automatic timezone setting

* automatic time set: rename MAKEFILE_ to BUILD_ to match gossamer

* Revert "Added default location"

This reverts commit c24f69450fd40472c4f6cebb790a56c3f0d69cb6.

* silence warning

* watch_get_init_date_time: explicitly initialize all fields to 0
