Improve parsing of rfc3339 strings

See merge request !3

There has been errors when using aw-server-rust because it uses
nanosecond precision for its rfc3339 strings while pythons fromisostring
function can only parse milliseconds. This change fixes this by adding a
new helper function parse_rfc3339 which discards the nanoseconds.

enable auto synchronization

this makes calling refresh() always focus the right day

catch them at caller level instead

Sets datetime format to rfc3339 subset of iso8601

See merge request !1

- Using rfc3339 fixes compatibility with aw-server-rust
- Renamed time.py to timeutils.py to avoid confusion with the built-in python
  module also named time
- Removed TimeUtil class as it served no purpose anymore
- Print callstack rather than just error message in exception handling

still hacky and WiP

not needed on platform 3.34

better error handling
