A calandar viewer for stalwart calandars

**NOTE** while this app uses standard caldav reading it makes assumptions about paths and treats them as if they all come from stalwart

**TODO**
1. Switch over to a golang caldav library, while I wanted to roll my own CalDAV I am too lazy to read up on the spec so imma just get someone else to do it
2. Fix password login
3. Actually write a UI that looks somewhat decent
