Hello, I wrote a patch to fix the issue of Kicad creating lock/PID
files for applications and open files in the user's home directory,
which is unsightly and wrong according to the XDG[1]/Apple[2]
standards/spec.
To fix it I created a new function in common.cpp which fetches the
proper path to use using environment variables and a couple fallbacks,
and edited all calls to wxSingleInstanceChecker's constructor to use
it. According to wxwidgets's documentation [3] the constructor
*should* ignore that extra argument on windows since it uses mutexes
instead of lock files. In Mac OSX I used the standard user-specific
cache directory, choosing somewhat arbitrarily "org.kicad-pcb.kicad"
as the app bundle name, feel free to change it if you think something
else would suit better.
In any case, it does need testing in those platforms. It works as
expected on Debian Jessie.
