HTML email templates: restrict amount of visible hyperlinks

Users report that some HTML email templates are confusing due to the large
number of hyperlinks in them. They typically click the first thing they see
that looks clickable without actually reading what they are clicking on,
expecting that it all points to the same thing.

In pullrequest invitations, the pullrequest and changeset URLs should be
clickable, but the source and target repository should not: this is not what
you typically want to see when taking action on this mail.

Similarly in comment emails, the corresponding repository should not be
clickable.

Unfortunately, even if we remove the <a> hyperlink tags on these repository
URLs, most mail clients will still recognize the text as being URLs
and make them clickable anyway. Worse, they will do so in a different
styling than the other links.

Therefore, do add <a> tags in the HTML, but make use of styling like that of
data_style, i.e. regular text color, grey background with dark grey border.
The links _will_ thus be clickable but it will not be as inviting as before,
thus removing confusion.

Debugging Kallithea
===================

If you encounter problems with Kallithea, here are some instructions
on how to debug them.

.. note:: First make sure you're using the latest version available.


Enable detailed debug
---------------------

Kallithea uses the standard Python ``logging`` module to log its output.
By default only loggers with ``INFO`` level are displayed. To enable full output
change ``level = DEBUG`` for all logging handlers in the currently used .ini file.
This change will allow you to see much more detailed output in the log file or
console. This generally helps a lot to track issues.


Enable interactive debug mode
-----------------------------

To enable interactive debug mode simply comment out ``set debug = false`` in
the .ini file. This will trigger an interactive debugger each time
there is an error in the browser, or send a http link if an error occurred in the backend. This
is a great tool for fast debugging as you get a handy Python console right
in the web view.

.. warning:: NEVER ENABLE THIS ON PRODUCTION! The interactive console
             can be a serious security threat to your system.
