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

`dev-notes` are severely outdated.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

-* 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.)

-
-  update buildschedulinginfo set priority = 200 where id = <ID>;

-  - Set HYDRA_DATA to /somewhere.
-  
-  - Run hydra_init.pl
-
-  - Start hydra_server
-
-  - Visit http://localhost:3000/
