system-test: fix web font corruption

A recent patch added bootstrap support, which includes embedded fonts
for icons.  While other packages handled these additional files correctly,
the system-test deployed "filtered" versions of the font files, resulting
in browsers rejecting the fonts and deplaying the characters with a
regular font.

This patch ensures that the web-fonts, CSS and javascript files are not
affected by dCache filtering.

dcache alarms: add properties and fuller documentation for configuring SMTP appender

The instructions in the current logback-server.xml are
incomplete in terms of how to set up the appender to
talk to a normal SMTP server.

This patch is a revision of http://rb.dcache.org/r/6945
which exposes all of the configuration through the
standard dCache property framework.

This means that the patch is more invasive,
with code slightly modified in a few places.

A separate patch adding the fuller settings to
logback-server.xml without property changes
has already been posted for backport and merged
in (2.6, 2.7, 2.8 and 2.9).

Testing: Used new properties to configure send through gmail SMTP
to two fnal email recipients.

Target: master
Require-book: yes
Require-notes: yes

RELEASE NOTES:  Fuller documentation for the configuration
of the alarm server's logback appenders (particularly for
email notification) has been provided.  The logback
settings are now fully configurable through the properties
framework.
