Added 'PageType' infrastructure to PageAccess, which basically
informs the rest of the system about how a page of address space is to be treated (READ, WRITE, READWRITE). This makes it much easier to track if a read from the write port has occurred. As such, the _rwport command should now be somewhat faster. Eventually, the debugger/disassembler will use this info to colorize the output. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2004 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
