No implicit <Directory> entry for ScriptAlias path

Support for ScriptAlias currently implicitly and automatically creates
<Directory> configuration directives for the path component in a given
ScriptAlias directive. These are not useful or needed, according to the
mod_alias documentation. Fixes issue #486.

This change also indirectly relates to #487 because the implicitly
created <Directory> entry for each ScriptAlias path also had
`SSLOptions +StdEnvVars` set for that directory.

No implicit <Directory> entry for ScriptAlias path
Set SSLOptions StdEnvVars in server context

We set `SSLOptions` now in server context and we set it to `StdEnvVars`.
Thus, we no longer need the <FilesMatch > in server context to set it
for php, CGI and SSI applications.
We allow it to be overridden by the `apache::mod::ssl` class parameter
`ssl_options`. Further, we allow it to be overridden in directory
context.
Documentation for all of these has been extended and tests have been
adapted to make sense in this new context. This commit fixes #487
Add support for ScriptAliasMatch directives

Much like in PR #483 extend the _scriptalias.rb template so that the
`scriptalias` parameter in `apache::vhost` can contain `aliasmatch`
hashes which get translated to `ScriptAliasMatch` directives. Fixes
issue #480.

Includes basic spec tests and updated documentation in README.md.

Note again that puppet-rspec silently drops `$1` when specifying test
values so we match `FOO` instead of `$1`. From a simple spec test
perspective there shouldn't be a difference and this is better than
having no tests at all.

Add suPHP_UserGroup directive to directory context

suPHP_UserGroup is only supported in per-direcctory context. We add this
directive analogous to the per-vhost suphp_ directives, by making sure
that suphp_engine is actually enabled.

  suphp => { 'user' => 'myappuser', 'group' => 'myappgroup' }

With documentation and tests in place, this should fix #451

No trailing slash for ProxyPass/ProxyPassReverse

Remove implicitly added slashes in ProxyPassReverse location paths.
Trailing slashes should either be present on both path and url, or
absent on both. Mixing one with the other is bad. Should fix issue #511.

Make LogLevel configurable for vhost

Add a `log_level` parameter, which defaults to `undef`, in
`apache::vhost` to allow overriding the global server configuration's
log level (warn) on a per-vhost basis. Includes updated documentation
and basic spec tests. Fixes issue #510.
Test that proxy_pass works

Given a `proxy_pass` statement for a vhost, it should be able to proxy
requests to another destination. This requires the proxy_http mod.
