the slight mismatch in hashtag regex between js and ruby was causing
hashtag warning to be displayed for unlisted tweets when an invalid
hashtag was entered

exact version of ruby regex not possible in js as POSIX bracket
expressions are not supported, this version approximates and doesn't
give same unicode support

* upgrade vagrant box to xenial

this allows the redis version to be upgraded to support the new redis
features used in the activity tracker

* add libpam0g package to vagrant box

this is required for native extensions of gems to build after the
addition of PAM support was added in #5303

* Add option to show only local toots in timeline preview
Right know, toots from all the known fediverse are shown in the main
page of an instance. That however doesn't reflect the instance itself.
With this option the admin may choose to display only local toots so
that users checking the instance get a better idea of internal
conversations.

The database and Redis do not need external connections, so isolate them
and prevent unauthorized access.

It is required for ApplicationController.

* added save back to the bottom

* Update show.html.haml

They were redundant, and also had a inconsistency; the button for
"other instances" had an icon for the external link in "more" page, but
it didn't in the other pages.

This unifies the implementation, and the external link icon is now shown
in all the about pages.
