Merge 64 and 32-bit versions of Linux and Windows installers
Right now, the Railo Windows installers have been merged into 1 install file. This simplifies both the installer selection and usage but results in a slightly larger download file (from about 100MB to about 130MB).
This should be more acceptable when we add the option to torrent the file, so we should do this because it will also speed future development by making file trees simpler.
The main difference is just the JRE, and including the JRE for each bit type into the same installer.
