Currently only ISO 8601 supported.

Needs a more powerful API in `FilterService`. See #15.

Analytics transforms `date` to `billing`, so applying the same filter does not work here. Think about if that feature won't end up confusing the user and myself too much :(

Operations: * add token to filter * functional operations on tokens * build/escape regex * properly quote tokens when necessary Used by: - analytics click handlers - transaction list label...

For irregular, but long-term payments, such as: * fuel * contacts * phone bills

For now, until proper presets are useful.

This is only about the code/resources. To make it actually useful, concurrency has to be considered (#25), which enables a local persistent model that can be saved without a connection,...

Use angular environment file to specify `/api` or `/api-dev`. Bind `/api-dev` to local dev files, write deployment script that loads files from git repo into the prod directory.

Purpose: Purely cosmetic display in list, to notice when going through transactions ones I already touched. Should be manually editable anyways.

Use cases: * Warning on `beforeunload` * Warning before refresh
