fixed title on album page(previously "artist"), added mysql-native substring search of album and artist names to internalSearch route, AJAXified web site (only contents of main-container, user functions are thankfully only in the header and are thus not affected).

    I can either test how the AJAX might break the php session, or I can try to implement the thing that would be broken by it and find out directly. :)
