replace gorm

[fallenhitokiri]

Gorm has proven to be unreliable when it comes to migrating a database or doing basic things like silently dropping inserts / updates.

SQLite showed to be annoying when it comes to cross-compilation.

There are two potential ways to solve this problem:

• stick with SQLite and replace gorm with sqlx (and likely add a few build systems once the first stable version is released)
• switch to a different data store that can be embedded (tiedot seems to be the most promising option right now)

The two most likely options right now

1. bolt + storm
2. in memory + JSON persistence
