This commit fixes #300.
Release 0.9.0

Summary:
This release adds more parameters to the base apache class and apache
defined resource to make the module more flexible. It also adds or
enhances SuPHP, WSGI, and Passenger mod support, and support for the ITK
mpm module.

Incompatible Features:
- Remove many default mods that are not normally needed.
- Remove `rewrite_base` `apache::vhost` parameter; did not work anyway.
- Specify dependencies on stdlib >=2.4.0 (this was already the case, but
  making explicit)
- Deprecate `a2mod` in favor of the `apache::mod::*` classes and
  `apache::mod` defined resource.

Features:
- `apache` class
  - Add `httpd_dir` parameter to change the location of the
    configuration files.
  - Add `logroot` parameter to change the logroot
  - Add `ports_file` parameter to changes the `ports.conf` file location
  - Add `keepalive` parameter to enable persistent connections
  - Add `keepalive_timeout` parameter to change the timeout
  - Update `default_mods` to be able to take an array of mods to enable.
- `apache::vhost`
  - Add `wsgi_daemon_process`, `wsgi_daemon_process_options`,
    `wsgi_process_group`, and `wsgi_script_aliases` parameters for
    per-vhost WSGI configuration.
  - Add `access_log_syslog` parameter to enable syslogging.
  - Add `error_log_syslog` parameter to enable syslogging of errors.
  - Add `directories` hash parameter. Please see README for
    documentation.
  - Add `sslproxyengine` parameter to enable SSLProxyEngine
  - Add `suphp_addhandler`, `suphp_engine`, and `suphp_configpath` for
    configuring SuPHP.
  - Add `custom_fragment` parameter to allow for arbitrary apache
    configuration injection. (Feature pull requests are prefered over
    using this, but it is available in a pinch.)
- Add `apache::mod::suphp` class for configuring SuPHP.
- Add `apache::mod::itk` class for configuring ITK mpm module.
- Update `apache::mod::wsgi` class for global WSGI configuration with
  `wsgi_socket_prefix` and `wsgi_python_home` parameters.
- Add README.passenger.md to document the `apache::mod::passenger`
  usage.  Added `passenger_high_performance`,
  `passenger_pool_idle_time`, `passenger_max_requests`,
  `passenger_stat_throttle_rate`, `rack_autodetect`, and
  `rails_autodetect` parameters.
- Separate the httpd service resource into a new `apache::service` class
  for dependency chaining of `Class['apache'] -> <resource> ~>
    Class['apache::service']`
- Added `apache::mod::proxy_balancer` class for `apache::balancer`

Bugfixes:
- Change dependency to puppetlabs-concat
- Fix ruby 1.9 bug for `a2mod`
- Change servername to be `$::hostname` if there is no `$::fqdn`
- Make `/etc/ssl/certs` the default ssl certs directory for RedHat
  non-5.
- Make `php` the default php package for RedHat non-5.
- Made `aliases` able to take a single alias hash instead of requiring
  an array.

Convert sendfile param to string from bool.

Currently, one would assume that since the default is false, setting `sendfile
=> true` would cause the option to be enabled in httpd.conf, but instead it
writes `sendfile true` which is incorrect.  This makes the usage consistant
with commit a82af5595e1e51961903873b6171bd5e08857d60.  Includes rspec
tests and input validation.
