This preserves `<a ... class="u-url mention">` from other Mastodon instances.

Steps to reproduce the original issue:
1. Have two remote accounts, A that you don't follow, and B that you follow.
2. Have A post a toot and reply to it.
3. Boost A's reply from remote account B.

This used to cause the local instance to get A's reply but fail to link it to
the original post.

* Sort results by the name
* Switch search method to simple `LIKE` matching instead of tsvector/tsquery

Previously we used scores from ts_rank_cd() to sort results, but it didn't work
because the function returns same score for all results. It's not for calculate
similarity of single words. Sometimes this bug even push out exact matching tag
from results.

Additionally, PostgreSQL supports prefix searching with standard btree index.
Using it offers simpler code, but also less index size and some speed.

- Use yargs instead of minimist
- Simplify validators
- Fix typo (RFC5626 -> RFC5646)

* Try fixing ThreadResolveWorker calls

From my understanding of ActiveRecord, a transaction is commited as soon as
the exit of the outmost ActiveRecord.transaction block. However, inner
transaction blocks will exit without the transaction being commited.

In this case, ThreadResolveWorker were fired *within* a transaction block,
so moving the call out of it should do the trick. However, this is somewhat
fragile, as this whole codepath could be called within yet another transaction.

* Set status thread within the transaction block if it is immediately available from database

* Add streaming_api_base_url to /api/v1/instance

* Adjust spaces

* nested view

* re-adjust spaces

* Extract StatusThreadingConcern from Status

* Clarify purpose of checking for nil account

* Fix #3550 - Add all missing foreign keys

* Add missing foreign keys

* Redirect to streaming_api_base_url

When Rails receives a request to streaming API, it most likely
means that there is another host which is configured to respond
to it. This is to redirect clients to that host if
`STREAMING_API_BASE_URL` is set as another host.

* Use the new Ruby 1.9 hash syntax

* Add support key shortcut to Onboarding Modal

* this.state.pages -> this.pages
