CURA-4741
With the multi build plate feature, scene.gcode_list is now a dict which
stores a list of gcode for a build plate, so it makes more sense to have
it renamed to "gcode_dict" because it's not a list.
This reverts commit b62c19206f5e494fa27eb0b877197556c559e449, reversing
changes made to 104926c6ed1648ec20b4308fdacad4e99c14c8b3.

homing the head with "G28" does not work on my printer for some reason. "G28 X" and "G28 Y" however do.
this fix should not break behaviour on other printers as "G28" is just a shortcut.
On printers that home the bed to the bottom (ie: printhead moves towards the bed), homing the bed when aborting a print could cause the printhead to crash into the aborted print.
When the time passes normally it doesn't trigger this signal but just go on counting, but when the pre-heat starts or cancels it updates via this signal. This is handy for the future, when we want to update the remaining time from the printer information. However for now it is also nice because we can make the pre-heat timer dependent on this signal so we know when to have it running. This fixes the problem that the pre-heat seems to have been cancelled in the GUI when you switch away the tab, because the timer running is now dependent on the property rather than always false.

It just calls the bed heating command without implementing the time-out. Implementing the time-out is impossible via just g-code.

As address it uses the serial port, which would be COM# for Windows and /dev/ttyUSB# for Linux. I don't know what it would display there on OSX, probably a drive directory.

Looking at the old code shows that the download process was never
completely finished. The according function was only return'ed, but no
signal was emitted to the window to give the user the possibility to
close it again.
Optionally, it would be useful here to pass messages to the window
dialog to inform the user about problems.
However, this code is untested because:
1. I don't know where put my printers *.hex-file, when coding here with
my editor,
2. Have no idea how to reproduce the IO errors reported at JIRA, so
fingers crossed here.
