* Auto confirm remote accounts
  * Don't send out emails for remote account activation
  * Forbid password changes on remote accounts

This stems from a confusing similarity between the + operator for arrays
and array_merge() in php. Adding arrays will ignore items in the RHS where
keys are present in the LHS. Therefore, when adding numerically indexed
arrays together, only items on the RHS that have a key higher than the
greatest key on the LHS will be included.

Support adding remote user to an organization

Support adding existing or new users while on organization page.

Support searching both staff and user backends via a common interface.

Previously we required an account to associate a user to an organization.

Show user status on the user listing table

It is perfectectly fine to have an image cited in an HTML body similar to:

<img width=909 height=302 src=cid:image002.jpg@01CF5426.BF5A72A0 alt=image>

Which may or may not have quoted @src attribute, and may very well have an
at sign (@) somewhere in the attribute text. The previous regular expression
would not match such a @src attribute.

This will make upgrades from osTicket < 1.8.0 substantially faster and more
reliable, considering that the previous ticket threads will not need to be
explicitly converted to html.

Thread entries now have a flexible `format` specification, which allows the
system to save the format alongside the original text. This allows the
system not to have to convert everything to HTML when storing in the
database

The code introduced to convert the database values to PHP values introduced
a bug where the configuration would not be saved.

There was a major goof for osTicket 1.8.0 where the installer created a
`form_id` column in the `%filter` table; however, the upgrader neglected to
add the column. Therefore, users who have upgraded from a version previous
to 1.8.0 will not have the `form_id` column in their database whereas users
who installed osTicket >= v1.8.0 and upgraded will have the column. Since
MySQL has no concept of `ADD IF NOT EXISTS`, this dynamic query will
assist with adding the column if it doesn't exist.
