Added missing self(s)
Make separate tables for OLAP users an option
Use current feature/dynamic as benchmark basis
Removed doubly defined _createUsers

Possibly due to merge fuckup. I used the one from the current master.
Refactored default use of jemalloc in settings

Just adding jemalloc in the toString method of Settings does not seem like a
good fit to me. I made the setting more obvious and explicit. It broke up the
general print the entire array simply to a string and required explicit
handling of USE_JE_MALLOC key. Worth it.
Fix to correct number of runs

range describes [) not [] interval
Made separateOLAPTables parameter more visible
Update git submodule of hyrise before build
Exit if distinct/prepare query failed
Remove superfluous env setting
Reenable building of server
Use Settings for build correctly
Rebuild once at beginning of benchmark
Do three runs for varying mts
Test w/ and w/o separate tables for OLAP
Change order of experiments to match option numbers
