Fixed several little things and imported a bunch of ytdb stuff.  Haven't tested it all yet but so far so good.

- fixed bug in install script where if you specify a value it errors saying there is no command called 'whatever you entered'
- extended the linux install script to drop, create, give permission to the database
- extended the linux install script to import the 3 core patches needed for all the new ytdb updates
- removed primary key from zoneId in phase definitions to allow importing of some ytdb phase definitions
- imported two ytdb files 723_updatepack_mangos_12773.sql  724_updatepack_mangos_12803.sql
