Quick Patch - 0.3.1

Hey all,

Following a couple of issues noted by you I have made a quick patch.

• Full mount clipping issue has been addressed. The vertical spacer should not stick through the mount anymore.
• Runcam 5 sleeve has been modified to fit the camera better. (height and width reduced by 1mm, depth reduced by 4mm) further refinement may be necessary.
• MacOs is now supported, make sure you download the correct zip file. I can not test the mac version, in fact I have no idea how it will even run, but I was able to compile it so I will rely on those with Macs to let me know how badly I messed it up.
