Add possibility to exclude certain devices about fwup HOT 7 CLOSED

@mobileoverlord - FYI: this issue may affect the Nerves tooling. I'm still thinking of a solution. The backstory to this issue is that @philipgiuliani is running on a Raspberry Pi where the SDCard containing the OS looks a lot like an SDCard that fwup would like to program. Use of a configuration file came up while we were brainstorming possible solutions. I'm currently leaning towards being smarter with the auto-detect logic for this situation. That doesn't mean there wouldn't be a conf file, though. Also, I believe that we're swapped in how we ask the user to proceed. fwup defaults to not burning an auto-detected SDCard, and mix firmware.burn defaults to burning. We should probably make it consistent.

You could process the output of df to ignore the drive that's mounted at /.
I was thinking you could ignore anything that's in df, since the person wouldn't be mounting their SD card, but that's probably not as robust with Linux auto-mounting USB drives.

@philipgiuliani: I added detection of which drive is mounted at / to exclude it from the autodetect list. It's in the autodetect branch. Could you try it out? You can get a prebuilt .deb package for Raspbian here: http://files.troodon-software.com/fwup/autodetect/fwup_0.9.2-dev_armhf.deb. It will install fwup to /usr/bin, so if you've previously compiled from source, be sure to remove the one in /usr/local/bin.

@fhunleth I'm not at home, i'll try it out today evening.

It seems to have worked fine.

pi@philipdev:~/workspace/gardex/apps/fw $ mix firmware.burn
Use 3.69 GiB memory card found at /dev/sda? [Yn]

Awesome, thanks! :)

Great! Thanks for verifying. I'll merge the change to master for the next release.

I'm going to keep this issue open a little bit longer since the config file is still interesting. It has some ramifications, though, that need thought. If I don't get any great ideas before the next release, I'll close this and possibly open an issue solely regarding the config file.

I'm closing this issue, since I'm pretty sure that the original problem has been addressed. I'm not opposed to having a global config file, but I don't feel like there's enough motivation to spend time adding it (for me at least).
