Adding explicit instructions about /var/lock

[kigster]

This cost me at least 2 hours of wrestling until I stumbled upon this thread:
#129

I have a 64-bit version of jnlb serial library, but I was still not able to write to serial port until /var/lock was created. So I am adding a check for for MacOS and /var/lock being accessible so that nobody has to waste anymore time :)

If there are alternative means of removing this unfortunate stumbling block, feel free to reject :)

Change the text to "not accessible or already in use: try to quit all other programs that may be using it. If that doesn't fix it, please run the following command:"

Also, fix that it's actually quitting not quiting ;)

@alpha-ninja that's a great suggestion. Coming up with some refactoring :)

I have another big chunk of the serial code refactored here:
kigster@207d300

I'll submit that as a separate pull request later. But in the meantime any feedback is welcome!

Add some \n's to the mac error message. (\r\n is not required as this message only shown on mac anyway) It'd help everyone's eyes :P

[kigster]

@alpha-ninja it's already there in the latest commit.

as in add it to the text that's passed on to the log method. The readability improvement through concats is not what I mean

[alpha-ninja]

à la

Common.log(new Status(IStatus.ERROR, ArduinoConst.CORE_PLUGIN_ID, "Serial port " + PortName
+ " is not ... using it. THIS RIGHT HERE ---> \n"
+ " If that doesn't fix it, please run the following command:"
+ "\n\nsudo mkdir -p /var/lock && sudo chmod 777 /var/lock\n"));

I just wonder why I keep updating the faq : http://eclipse.baeyens.it/Arduino%20eclipse%20plugin%20FAQ.html#MAC_Lock
It should be the first place to look.
I guess you switched to arduino IDE 1.5.6 or higher. That means Arduino moved to JSSC see #67
Arduino removed the delivered RXTX libraries and as such you fall back on the plugin delivered libraries.
I have copied the RXTX libraries into the newer Arduino versions as I had some issues as well.
I give 100% priority to #67 right now so I will not accept these changes. Sorry for that.
