Installer component updates to match RFC89

[jng]

The current binary distributions used by the installer are considerably out of date and may not work with the changes introduced in RFC89. So the following components will be updated:

• Apache
• PHP

PHP will be updated to 5.3.2 (VC9 x86 Thread-Safe)

Apache will be updated to 2.2.11 (to match the version in Oem)

The official httpd site does not offer a VC9 binary, but one is available from ​http://www.apachelounge.com so we'll use the binary distribution from there.

To make way for a future x64 installer, these components will be put under Installer/Support/Web/x86 to indicate that these are 32-bit binaries

Tomcat will be moved from Installer/Support/Web/Tomcat to Installer/Support/Web/x86/Tomcat

Build scripts will be updated to ensure the staging area is prepared from the updated location.
