Subject: Auto detect language based on locale
X-Git-Tag: lulzbot-15.02.1-1.01~75^2~2
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=f32e43b1bcf6a7d18e5b5ef8cc10367452537bf9;p=cura.git

Auto detect language based on locale

This wasn't tested on Windows, but the code is in a try/except and
will fallback to using the default locale if it fails.
Fixes issue #29
