doc: drop dev-notes & make update-dbix more discoverable

`dev-notes` are severely outdated. I dropped everything except one note

-  $ make -C src/sql update-dbix
-
-* Running the test server:
-
-  $ DBIC_TRACE=1 ./script/hydra_server.pl
-
-* Setting the maximum number of concurrent builds per system type:
-
-  $ psql -d hydra <<< "insert into SystemTypes(system, maxConcurrent) values('i686-linux', 3);"
-
-* Creating a user:
-
-  $ hydra-create-user root --email-address 'e.dolstra@tudelft.nl' \
-      --password-prompt
-
-  (Replace "foobar" with the desired password.)

-  To make the user an admin:
-
-  $ hydra-create-user root --role admin
-
-  To enable a non-admin user to create projects:
-
-  $ hydra-create-user root --role create-projects
-
-* Changing the priority of a scheduled build:
-
-  update buildschedulinginfo set priority = 200 where id = <ID>;
-
-* Changing the priority of all builds for a jobset:
-
-  update buildschedulinginfo set priority = 20 where id in (select id from builds where finished = 0 and project = 'nixpkgs' and jobset = 'trunk');

-
-* Steps to install:
-
-  - Install the Hydra closure.
-
-  - Set HYDRA_DATA to /somewhere.
-  
-  - Run hydra_init.pl
-
-  - Start hydra_server
-
-  - Visit http://localhost:3000/
-
-  - Create a user (see above)
-
-  - Create a project, jobset etc.
-

-    php-sat:build [same system]
-    tarball [same patchelfSrc]
-    --if system i686-linux --arg build {...}
