orm: Add PK field check for DISTINCT aggregate expressions

When using the DISTINCT option for aggregate expressions, ensure that when a
relationship is used in the aggregate, that a single field of the remote
model's primary key is used — rather than the foreign key, since it would
never have more than one unique value.

Thanks for the hint Peter.
Changed it (again) and also tested at our system. /scp/slas.php works as intended - so only the slash "/" before "scp/slas.php" was missing.

Hi guys,

here is a catch from the forum: http://osticket.com/forum/discussion/78661/invalid-sla-link-on-popup-help-tips

Since scp/ seems automatically added before slas.php just changed
scp/slas.php to slas.php

Quickly tested it and link works correctly after that little change.

Ticket numbers are now configurable as a system-default and by help topic.
Previously, an administrator could select between six-digit random and
sequential numbers. Now, the sequence is selectable so multiple sequences
as needed, and a format can be specified to define how the ticket numbers
look. Formats can also be defined for each help topic.

- Proofread large portion of help tips.
- Implement help tip links in YAML files.
- Fix GUI spacing of some elements.
- Add <label> tags to a few form elements.

  * Drop _table_ titles
  * Drop _button_ titles and contents
  * Fixup titles to remove leading and trailing underscores in titles
  * Remove duplicated namespaces for ticket queue pages
  * Whitespace cleanup
