This is slightly more efficient on the CPU, while not making any
visible difference to the user.

The most recent Phosphor commit c141d8f unified the is_cursor_visible
and cursor_icon callbacks.

Some frames would sporadically lag between on_process and on_render,
because on_process would bail once one frame had elapsed since the end
of the previous on_process, and the processor would not always reach a
sleep point in this time. This was really an issue to do with with the
time taken between the end of the previous on_process and the start of
the current on_process.
To fix this, the on_process invocation will run the processor for a full
frame, without subtracting the time elapsed between frames. This seems
to have no negative effects. It also allows us to remove end_of_process
from the emulator.
The sleep in the Signal::Sleep handler has also been removed, because
it serves no real purpose and will most likely cause issues in the
future.

The window title of the emulator can be set when constructing a new
instance of the emulator. This is useful when a Bedrock program is
baked into the emulator for distribution.

The program is vastly more efficient to run, consuming only 1.5% CPU
instead of 13% during testing on Windows 10. Input events are handled
four times as frequently now, which makes for smoother lines when
drawing in Cobalt.

Without this, text pushed to the stream device before a debug
instruction would often display after the output for that debug
instruction.

There was confusion between the role of the page_limit variable in the
memory device, where it was being used to mean both the absolute upper
limit of pages that are allowed to be allocated, but also to mean the
number of pages that the program would like to be allocated when needed.
To fix this, the program is now just told the full number of pages that
it is allowed to use, without first requiring that the program request
a particular number of pages.

The memory device was never being allocated any memory, the input device
wasn't scrolling correctly, the screen device was rendering sprites
incorrectly, and the device ID of the file device had not been changed
over from 0xA to 0x9.
