Import from SQLite database

[NetDwarf]

Add check for file_path option in config.yml Extract import database logic into own interface/types (sqlProvider for mysql and sqlite) Sort json data by primary key to make it repeatable Rename source files to export.go and import.go respectively

To make sure that the outcome didn't change, because of different sorting, I did this:

• go run . -export mysql
• echo "DROP DATABASE IF EXISTS dol; CREATE DATABASE dol;" | mysql [credentials] --database=dol < public-db.sql && mysqldump [credentials] dol > dump.sql
• remove last line of the dump (time stamp)
• md5sum dump.sql
• git checkout upstream/master and repeat

The check sum should be and was the same.

Regarding the testing of import option the testing was straight forward.

• git run . -export [exportType]
• import resulting sql into mysql/sqlite database
• go run . -import with specific config.yml (either with file_path or mysql credentials)
• see that nothing changes (e.g. git diff)
• do the same for either database type (sqlite + mysql)

Just for sanity I also did change a single entry to see if it is mirrored in the import. (it was)
