Clean up the browser about URL handler to not derive from WebContents. It is

instead integrated in the BrowserURLHandler for special schemes. This solves
a number of problems and cleans things up nicely.

Most of the functions were not necessary to have in the header file of the
browser about handler, so I made them local to the .cc file. I moved everything
around, but there was no change to any of the About...() functions.

This improves the about:memory page to not include the memory of the new tab
page it replaced. The entry for itself also has the proper title. This works
by using a meta refresh to the actual page, the the process transition no longer
happens at the same time as the about:memory page computation.

This also fixes problems with the about:network and about:ipc dialogs opening
blank pages and also re-opening the dialog when you close the browser.
