* Rescue when there's no extension in the remotable
Sometimes the remotable is pointing to a directory with no file
extension. Maybe it should not be expecting to identify based on
extensions to begin with, but since it's the case, it should be ready
for it.

Various preformance and stability enhancements for instances deployed via Nanobox.

Both of yarn and npm are used in Mastodon, but the combined usage requires
a redundant dependency and may lead to data inconsistency.

Considering that yarn has autoclean feature which npm does not have,
this change replaces all npm usage with yarn.

This change requires documentation update. Most notably, the following
command must be executed before assets precompilation if any system
dependency of node-sass has changed:

yarn install --force --pure-lockfile

UI component used to toggle isComposing state by directly manipulating the
DOM element to avoid the expensive rendering.

However, it is hacky, and is not effective for other states. Instead,
this change makes the rendering cheaper by extracting the huge columns
area.

TabsBar refers to router, which is a private context property of
react-router. withRouter is a recommended alternative. It also allows to
track location changes even if React.PureComponent is used.

But do not upscale when they are smaller

onScrollToBottom was a function to run instead of onScrollToTop and
onScroll when scrolling to the bottom. The behavior to prevent
onScrollToTop was inconvenient because the viewport can be at the bottom
and at the top at the same time if the viewport is larger than the
container.

onScrollToBottom was also called when the button to load more is clicked
on contray to the name suggests, which led notifications and
status_list_container components to mark the scrolled location is not at
the top mistakenly.

onLoadMore is a replacement for onScrollToBottom. It will be called
independently from onScrollToTop and onScroll.

This is also implemented in Pawoo:
https://github.com/pixiv/mastodon/commit/ceafdbd1bbf30fe20a2a814df0f8cae429a4e9db

When volumes are declared, but the corresponding directories don't exist, permissions for those directories will be root:root instead of mastodon:mastodon..
This changes makes sure the permissions of the volume directories are as expected.

site_title is "Mastodon" by default configuration, and there is no need to
default site_title with site_hostname in InstanceHelper.

They are already required by common.js.

This is a functionality similar to one implemented in Pawoo:
https://github.com/pixiv/mastodon/commit/21a3c70f8083b1347d2b8420ed7001b78c2c9620

The default locale is now set by config.
