break the predefined requirement of the schema name being "stevedb"

this work goes over the all migration scripts and removes every occurrence of "stevedb". now, the schema name is configurable by user. furthermore, it cleans up the initial mysql dump (V0_6_6__inital.sql). if the schema does not exist, it will be created by the flyway using the given schema name.

+### How can I upgrade from 1.x.x to 2.x.x? ###
+
+The major release 2.0.0 is backwards incompatible with existing installations,
+since the migration scripts are manually altered (See commit message: TODO) and the checksums in the metadata
+table of Flyway (our DB migration tool) need to be corrected.
+This can be done executing the following command:
+
+    mvn initialize flyway:repair
