Aligned CustomerID field for AgentTicket(Phone|Email)
Speed up Kernel::System::TemplateGenerator

When replying to an email of size 3.2MB, AgentTicketCompose
spent nearly 44s in Kernel::System::TemplateGenerator->_Replace.
This patch reduces the time to about 11s on my dev system.

As an added bonus, it reduces the code size and removes
code duplication.
Tidied code.
Fixed bug#9737 - Sort order in queue view labelled incorrectly for all columns except age.
Re-added very useful test file. Now skips test if custom configs are installed to avoid wrong errors.

Fixed Redirect on IIS 7 web server.

The redirect had a double slash, this caused a redirect to the login screen
if you use session cookies.

This patch removes the double slash.

The redirect is no longer needed for IIS 7 and up, so the workaround is now
only applied for IIS6 (IIS5 came with Windows 2000 Server and is no longer
supported.)
Fixed typos.
