init of passenger module
set a global passenger buffer dir

with passenger 2.2.4 an additional buffer directroy have
been added, which have to be writeable by the apache process
running as apache user, as it is seperated from the application
process as used for fileuploads.
Added Debian support for apache passenger
merge with shared-modules/passenger
have passenger_stats munin script take an environment variable for the location of passenger-status
add a variable $passenger_bin_path to the passenger class
on newer debian systems, the package name for rack is 'ruby-rack' so this adds a
check to see if you are still on squeeze or not, otherwise it will use the new name
update README to be more current: adds parameterized class information, makes it clear that the munin module is optional
