[Lazarus] EmbWeb: Moving between webapp type caveats

I use an .ini file, but the same idea. There can be a lot of things that 
a web app needs as a constant.
static paths, email server settings, template paths, url generation 
parameters (https or http, ports for development computer, etc.), db 
connection settings, etc.
This way it is the easiest to move from a development environment to a 
live system. All you need is to remove the .ini file (or constants by 
defines), or change its values.
