plugins: fix typo (Muning::Plugin::HTTP)
Add a lower limit of 0 to postgres database size

This ensures that the graph always starts at 0 in stead of somewhere near the
smallest database size. This makes sure that database sizes are shown
proportionally correct.
Make the postgres_size_ y-axis behaviour configurable.
ignore 'INDIVIDUAL BUFFER POOL INFO' section in MySQL 5.5

If you set innodb_buffer_pool_instances to a value greater than 1 the status
will show a new section with details about each buffer pool instance.
I think the details a currently not needed so just ignore the section.
fix parsing file io for MySQL 5.5

In MySQL 5.5 the innodb status shows additionally aio reads and aio writes for
each thread in square brackets.
fix parsing insert_buffer_and_adaptive_hash_index for MySQL 5.5

master/limits: global default for always_send

On "nagios" and "old-nagios" contact, there is a default for the "always_send"
directive : "critical warning".

This commit makes it the default for *every* contact.
Remove use of removed Munin::{Master,Node}::Logger
use "eq" when comparing with undef
Merge remote branch 'pull/202' into devel

Merge pull request #206 from steveschnepp/fix-always_send

master/limits: global default for always_send
p/diskstats: enable warn levels in conf

Now we can configure the warning levels on disk latency directly via the node
configuration file.

Note that we reuse the previous value as a default.

Graph system peer's stratum

Although not ideal to dual purpose the state axis as stratum for this field, I don't think it warrants a separate plugin. Also, it is only enabled if env.show_syspeer_stratum is set (similar to env.lowercase). Especially with the use of NTP pools, this also allows for warn/crit levels if the esystem peer's stratum becomes above an expected stratum.
