This commit addresses inconsistencies on how field edit rights and
visibility are are handled.

This commit ensures that we will always get the correct attachment name regardless of if the file content is the same. Additionally, it ensures that the file_ids for attachments are compared in the correct order (elseifs)

This commit updates a bunch of files and changes a lot of phrases. Basically it extracts "Internal error occurred" from existing phrases.
I've re-ordered the phrases so "Internal error occurred" is always at the end after the actual informative error message.

Example comparison before and after this commit:
Before: 1 Phrase: "Internal error: Unable to print to PDF"
After: 2 Phrases: "Unable to print to PDF." + "Internal error occurred"

This pass also makes a stride at adding correct punctuation and making error
phrases consistent.

This is my attempt at removing similar texts from the translator work load.
It also makes an attempt at dropping some misspelled words and works toward
standardizing some phrases.

This feature allows (by option) an organization to allow its members to see
tickets from other members. It can be used beside or instead of the
automated collaboration feature. Now, collaborators retain access to tickets
on which they participate; however, sharing can be used to enable access to
other tickets owned by their organization.

And also fix mishap events changing the ticket status

Also log client edits as an event

This includes adding support to the Redactor editor to force the width of th
editable content to match the width of the displayed content on the client
portal. Also, the landing page displayed on the client portal is themed
(css-class wise) to match that of the Redactor content similar to the FAQ
and thread-entry designer boxes as well.

Reset field content when building a new form

Allow fields to be configured for view / edit / required for both agents and
end users. Fields can also be disabled now so that the field remains in the
form but is no longer displayed for new entries.

Allow tickets to be created without a subject — use the help topic full name
instead.

Add error/misconfiguration checks and fix undefined variables

Regardless of the configuration of the help desk registration, allow users
to receive ticket links via email. This patch enables the display and
operation of the ticket access link unless a user login is requested by the
user or specifically required by the system.

Client accounts now that the user is verified either via staff or the
client's email mailbox, there's a much lower risk to showing a verified user
other tickets and virtually no reason that an administrator should have to
turn the feature on.

Administrators can disable client edits of ticket information. Hopefully,
this will eventually be replaced by role-based ACLs placed on individual
forms and fields.

The concept of extid is being retired to pave-way for customizatable ticket
numbers.

 - This is necessary so we'll have a name on record - even on user deletion.

Pass the user id (uid) to ticket create instead of unpacked data.

Process inline attachments in thread entry and support inline images in
piped emails

Support inline images across the system, with draft support

Migrate to a single attachment table
    That way we don't need a new table for everything we need to attach an
    inline image to (like a signature, for instance)

Add richtext support for internal notes

Implement images on site pages

* Image paste in Redactor
* Make non-local images optional
* Placeholder for non-local images
* Fix local image download hover
* Don't re-attach inline images
