Add "Advanced" option to reset the database #345
Description
It should not happen that the Dopamine.db contains incorrect info. However, an indexing bug could lead to such situation. When it happens, users must manually delete their Dopamine.db file. To avoid having to tell users the manual steps to delete their Dopamine.db and to make his process easier for them, add an "Advanced" option to reset the database. Provide a confirmation window that clearly states that all info will be lost.
