New class: pynag.Parsers.MultiSite

Behaves like pynag.Parsers.mk_livestatus() except it supports
multiple livestatus instances
MultiSite - Fix get_statistics for multiple hosts

Also includes documentation patches
Skipt MultiSite tests in travis

We dont even have livestatus installed in travis
Synchronize ClassName style in Parsers

Some classes like config and mk_livestatus have been written
in lowercase since forever.

The following renames have been done:
config -> Config
mk_livestatus -> Livestatus
retention -> RetentionDat
status -> StatusDat
object_cache -> ObjectCache

The old classnames will still work (forever?) but the
new names can be used right away.
