replace PHP include statements with Jekyll templating language equivalent.
renamed includes dir to _includes to conform with standard jekyll directory layout.
moved search_include.html file into the includes directory.
fixed paths in include tags.
added several file types and directories (including the default jekyll build directory _site) to the gitignore list.
renamed htdocs dir to src. this should prevent confusion about the true nature of this directory. its a source dir, not a webroot.
added front-matter delimiters to page-level templates.
removed obsolete ForceType declaration from .htaccess file.
