stamp 0.3.2-dev
Merge branch 'production'

Conflicts:
	pganalyze-collector.py
Add Linux cpuinfo workarounds for kvm
update gitignore for the fact that we switched to python
add linux cpuinfo tests as well as symlink with python-friendly module name
Send units of settings too because of entertaining unit potpourri
drop pg_table_is_visible to get tables in _ALL_ schemas

we already exclude uninteresting schemas
Handle exceptions with retrying while posting data
Ignore queries generated by the collector

Rudimentary logic to exclude queries to pg_stat_plans already existed,
but this didn't suffice. We now mark all queries with a constant
which we then later exclude.
Stamp 0.3.2 release
