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.

This support was included when filtering for USB only, but not the case when we are not filtering. I don't like this bit of code much since we should just define a list of paths to check and iterate over it, so that we can re-use the data and prevent syncing mistakes like this.
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.

* Removing unneeded import of "os"
* Removing unused "e" from SerialException
* Adding #@UndefinedVariable tags for PyDev
* Making message in Logger.log more detailed for portList(). Might be confusing in the logs to see just a list of ports without knowing where it is from.

The simple string replacement left an extraneous "/" in front of the path, which Windows can't handle. QUrl.toLocalFile() does a proper conversion.

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.
