Lua script and VHost.conf for generating mass virtual hosting environment like "user_dir" with "auto-map" on PHP5-FPM

Create unix users and add www-data to theyr groups.

Chown directories /srv/projects/projectname/workingspace to users and crate fpm-pools and put ports for fpm dependent on projectname in fpm-socket-ports-by-project-name.txt

fpm-socket-ports-by-project-name.txt

mass_vhosting.lua

--[[ Script for generating mass virtual hosting environment like "user_dir"

Features:
		Automatic detection and mapping on php5-fpm pool
			currently with RewriteMap based on projectname => port Key-Value txt file,
			by merging unix socket functionality for mod_proxy_fcgi RewriteMap is not needed anymore and
			then row 28 can be replaces with:
			RewriteRule ^/srv/projects/([^/]*)/(.*\.php(/.*)?)$ fcgi://socket=/path/to/$1.sock/./srv/projects/$1/$2 [P]
			.

Ideas:
		Switch DocumentRoot for webspaces(VHosts) relative to defaults with database/KV-heaps
		(See f.e. MySQLs "MEMORY Storage Engine" -> http://dev.mysql.com/doc/refman/5.5/en/memory-storage-engine.html )

		Make "projects" replaceable by configuration.

https://gist.github.com/RafaelKa/6471345#file-lua-local-dev-conf-L26-L29 fixes problem with order of execution:
without wrapped like here https://gist.github.com/RafaelKa/7302c4e934c13a710694#file-dynamic-php-fpm-conf-L22 LuaHookTranslateName comes not to executing code and DocumentRoot is then /var/www (also default)
