Initial roughing out of some profiling context

Browse Source 
wcat binaries (http://www.iis.net/community/default.aspx?tabid=34&g=6&i=1466)
Orchard.Profiling project to hold some wcat scripts for generating stress-style load and specflow features for generating fixed sets of requests
"add profiling data" command in Orchard.DevTools to create a number of samples page and blog content items
"build.cmd profiling" target creates build\Profiling web dir from clean build, and execs baseline setup and population via orchard cmdline

//
//--------------------------------------------------------------------------
// Optional:
//
// Additional machines can be monitored by adding more counters blocks.

// Example:
//
// counters {
// host = "sqlserver"; // name of remote machine
// interval = 5;
// counter = "...";
