[arch-general] Install Arch from network - Wiki page

Greetings to all. I made some changes to http://wiki.archlinux.org/index.php/Install_Arch_from_network_(via_PXE). This is my first contribution to Arch Linux wiki, and to any wiki pages. Can someone please check my work. I'm not expert Linux user, but I just finished install to some old lap-top over LAN and I found wiki paged incomplete and bit confusing. I'm also not native English speaker. I also fount this page http://wiki.archlinux.org/index.php/Tftpd_server, which I think describes similar thing, so I tried to merge both pages and I don't know if both pages are necessary. Sorry if this is not right place to write. Nebojša Stričević
