add basic Makefile with deploy target to run as root

This just installs a default mod_wsgi config file and a default
hatrac service config file. It will not overwrite existing configs.

+When using pattern replacement, srcfile is rewritten to a temporary
+before being installed to dstfile.  The replacment modes correspond
+to:
+
+   assign: replace shell script variable assignments such as
+      "key=rest-of-line" with "key=value"
+
+   ref: replace shell script variable references such as
+      "\${key}" with "value"
+
+   sed: replace using arbitrary sed pattern/value expressions
+
+The final mode specification applies to all replacements.
+
+Installation is handled by the regular "install" utility, which
+supports a target filepath or a target directory path for the
+destination argument. However, this script does not support the
