Changelog

Breaking changes:

c14b818 Fix CPU metric naming: merged user and system time into the single metric namedprocess_namegroup_cpu_seconds_total, with labels mode="user" and mode="system".
c3f6a04 Rename label cpumode in thread_cpu_seconds_total to mode, for consistency with namedprocess_namegroup_cpu_seconds_total.

Enhancements and fixes:

2f195b3 Restore -threads option removed in 990f810. Now the default is true instead of false as it was back then, so nothing should change from 0.4 unless -threads=false is given. Fixes #67.
d0323f9 Update to newer procfs to include fix for #80.
