Add installtion instruction

Good afternoon. as some of you may know, i am currently working on a new design for the php.net website and i came across the installation page[1]. the page contains information about "how to compile php from source" but no "how to install it" and i think this is not a good for newbies. when i started PHP as a kid, i remember using XMAPP on windows, not because i needed Apache or MySQL, but because the PHP site kept telling me that i need C runtime, VC CRT11 and then i should compile the source code and i didn't know how to do that at the time and everything seemed just complicated. for this, i suggest that w add a new "installation instructions" to the php website, and move the current pages to a new section called "compile from source". i have added installation instruction page in the mock ups of the new design, you might take a look at it here : https://github.com/azjezz/web-php-mock-ups/blob/master/screenshots/windows-installation.png [1] : https://secure.php.net/manual/en/install.php
