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.

Improve "make test-*", add verbose and test_files

 - Change default verbosity of tests to "not verbose"

 - Look for "test_verbose=" variable from command line to run tests in verbose mode.

   If the "test_verbose=" argument is set to anything, --verbose is added to the "perl Build test"
   command line.

   Example: make test-master test_verbose=1

 - Look for "test_files=" variable from command line to select test files to run.

   If the "test_files=" argument is set to a space separated list of files,
   test_files="<list of files>" is added to the "perl Build test" command line.

   Example: make test-node test_files="t/munin_node_proxyspooler.t t/munin_node_spoolreader.t"
