Fix mod::prefork dependencies

A dependency on the package resolves the following error:
"Error: /Stage[main]/Apache::Mod::Prefork/File_line[/etc/sysconfig/httpd
prefork enable]: Could not evaluate: No such file or directory -
/etc/sysconfig/httpd"
described the aliases parameter, but does nothing yet
Describe the directories parameter
This should put the aliases in a list after DocumentRoot, provided that .erb can handle hash["key"]
missing hash rocket  => in examples
create a template fragment for directories

...again I hope .erb hash processing works...
oops, missed a refactor.
missed refactor to directory
First character uppercase is not good for hash keys
ug, wacky repeating typos.

Use correct template for dav_fs module
Add proxy_pass parameter
Merge pull request #193 from oxilion/proxy_pass

Add proxy_pass parameter
Add $conf_template as a parameter to allow people to pass in a custom
apache conf if they really need to.  I've seen this requested about three
times this week in #puppet alone, so I figured I'd just do it and get a PR
up for it so it doesn't get forgotten about again.
added definition of allow_from to proxy configuration
made it so that certain required modules are always loaded, but only conditionally loading the rest based on the use case.  The "parameter" name kinda sucks, but it doesnt require a usage change for anyone.
