Add support for generic timeline (#525)

* Begin adding support for timeline

* fix some bugs with parser

* fmt

* add error reporting for parser

* add tests for timeline query parser

* add rejection tests for parse

* begin adding support for lists

also run migration before compiling, so schema.rs is up to date

* add sqlite migration

* end adding lists

still miss tests and query integration

* cargo fmt

* try to add some tests

* Add some constraint to db, and fix list test

and refactor other tests to use begin_transaction

* add more tests for lists

* add support for lists in query executor

* add keywords for including/excluding boosts and likes

* cargo fmt

* add function to list lists used by query

will make it easier to warn users when creating timeline with unknown lists

* add lang support

* add timeline creation error message when using unexisting lists

* Update .po files

* WIP: interface for timelines

* don't use diesel for migrations

not sure how it passed the ci on the other branch

* add some tests for timeline

add an int representing the order of timelines (first one will be on
top, second just under...)
use first() instead of limit(1).get().into_iter().nth(0)
remove migrations from build artifacts as they are now compiled in

* cargo fmt

* remove timeline order

* fix tests

* add tests for timeline creation failure

* cargo fmt

* add tests for timelines

* add test for matching direct lists and keywords

* add test for language filtering

* Add a more complex test for Timeline::matches, and fix TQ::matches for TQ::Or

* Make the main crate compile + FMT

* Use the new timeline system

- Replace the old "feed" system with timelines
- Display all timelines someone can access on their home page (either their personal ones, or instance timelines)
- Remove functions that were used to get user/local/federated feed
- Add new posts to timelines
- Create a default timeline called "My feed" for everyone, and "Local feed"/"Federated feed" with timelines

@fdb-hiroshima I don't know if that's how you pictured it? If you imagined it differently I can of course make changes.

I hope I didn't forgot anything…

* Cargo fmt

* Try to fix the migration

* Fix tests

* Fix the test (for real this time ?)

* Fix the tests ? + fmt

* Use Kind::Like and Kind::Reshare when needed

* Forgot to run cargo fmt once again

* revert translations

* fix reviewed stuff

* reduce code duplication by macros

* cargo fmt
