Updated the server script to support Redis when it has been installed via MacPorts. Also, fixed an echo error with it not being displayed correctly.

When using sub-uri, create a symlink in public/ making the assets
available at the sub-uri. Modify environment.rb so that asset paths
refers to this sub-uri path. Closes http://bugs.joindiaspora.com/issues/391
and http://bugs.joindiaspora.com/issues/737 when application mounted
on suburi (i. e., prev patch)

This reverts commit 9cd08bac.

Adds new routing in routes.rb based on pod_uri. Assets are handled by a symlink
in public when using sub-uri. Various clean-up, removing thin and socket port
settings from server.sh (these are now taken from pod_uri and socket_port).

Basic functionality when setting a sub_uri like http://example.org/diaspora
now seems OK. Closes .http://joindiaspora.com/issues/737, and partially
http://joindiaspora.com/issues/391. Ports are yet to be defined and handled
in this context.

Conflicts:

	config/routes.rb

Issue warning if there already is a running redis server, typically
the system server installed with the redis[-server] package.

See http://bugs.joindiaspora.com/issues/722

Not tested on BSD/Darwin, might need polish for these.

Creates config/redis.conf using mater copy in etc. FTM, disables
daemonizing, which doesn't fit script/server (or upstart/systemd).

Also, give slow starters some more time.

Wrong usecase. The real problem is always using the master branch.
There is no point using a files list, distributions will just
create the tar archive in advance.

This reverts commit 05410828.

On Fedora, logfile/loglevel in configuration file seems to be ignored
as of now.

Allows server to run even if on another branch than master and/or
in a production scenario without git files available.

This reverts commit 30698d67.

Introduces a delay first time the server is started, but makes all resources
available to jammit. Can be disabled by flag in config/server.sh. Hopefully
silences jammit's messages about application.css et. al. not found

This introduces some jammit warnings in 'rake spec'. These seem
to be just warnings. To get rid of them, take steps as described in
https://github.com/diaspora/diaspora/wiki/Installing-and-Running-Diaspora
in the "Read-only Installation" (sic!) chapter.
