Fix for Issue-52: Add support for runs comparison using new graphing module

Implemented the 'Compare' button in the results list. Select one or more
runs and hitting 'Compare' transfers control to RunAnalyzer which is the
main class for this feature.
Also added new class DetailReport to process the detail reports.
The result of the comparison is a xan file.

Allow using JDK 1.7 to compile faban.

In 1.7, specifying only the target version as was done in faban
build.xml is an error. If we specify source version instead, it
implies target and compilation succeeds. Doing it this way works with
JDK 1.6 as well (tested these changes with 1.6.0_21 and 1.7.0_25).

(Not sure if we really need to be compiling this to 1.5 anymore, but
I've left that unchanged for now. Can be upgraded later if desired.)

Also, build.xml was passing the same version to rmic 'stubversion'
which is incorrect (though it only generates a warning). The only
valid values for stubversion are 1.1 and 1.2, it doesn't take the full
range of JDK versions. Changed this to "1.2" which is the default.
Count down the latch allowing Agents to shutdown.
Fix handling of hosts for the common case where the hostname has no
dots. This broke recently with changes to issue-22.

When the initial hostname has no dots, dotIdx is -1. The
host.substring call then throws an exception and registration of this
host is bypassed.

While this section of code could be cleaned up further, a simple fix
here is to only attempt the substring if dotIdx is actually positive
(that is, if the host had some dots).
