Getting the print queue api working with the printer, adding a job progress panel to inspector and adding job_finished and job_started events.

Throttling the DOM writes of pronserve inspector and stopping dom writes entirely when the window looses focus.

Adding a sleep to the pronserve startup. Seems to be fixing an intermittent bug where the printer wouldn't respond to temperature requests

Refactoring Pronsole to wrap print in a self.log method so that it can be reused and overriden by a web interface or any other non-conosole interface

Show connection error to the user

Before, when there was an error while connecting, user didn't know, when
Pronterface wasn't launched from the terminal.

So you could just hit Connect button several times and all you've get was:
Connecting...
Connecting...
Connecting...

Now, when there is an exception during the connection, the user will notice:
Connecting...
Error: You are trying to connect to a non-exisiting port.

Or:
Connecting...
Error: You don't have permission to open /dev/ttyUSB0.
You might need to add yourself to the dialout group.

Unfortunately pyserial's SerialException doesn't provide errno yet, so the
message isn't so user friendly:
Connecting...
could not open port None: [Errno 2] No such file or directory: 'None'

I've filled a bug report with patch to pyserial.

Together with this I've realised, there is unnecessary UTF8 decoding of the
output. When user has UTF-8 locale, there was an exception when printing the
exception to the output (almost an exception inception). So I have dropped it,
but feel free to add it back, if I broke anything else.

gcoder.py reads the file content instead of the file name when testing

Previously, gcoder.py read not only the content of the file, but also it's
filename. This could have led to unexpected exceptions.

Added missing files to setup.py and fixed license notice in files which were not explicitly gplv3+.

If I install Printrun via setup.py, I don't have gcoder.py and I cannot even
use pronterface.py:

Traceback (most recent call last):
  File "/bin/pronterface.py", line 46, in <module>
    import pronsole
  File "/usr/bin/pronsole.py", line 23, in <module>
    from gcoder import GCode

So I've added this to setup.py.

Also, pronsole.ico is missing, added that to (not needed at runtime, but is
usefull for desktop files)

Conflicts:
	pronterface.py

added gcoder from another project. using gcoder to calculate dimensions and used filament

fixed measurement calculation for X and Y axis

Conflicts:

	pronsole.py
