Reordered Methods; Added ignore command (TODO change conConf->requestPath usage)
Refactored checkFSEntry, getFiles, setRequestPath; Removed requestPath magic
-Refactored "appendFileName" code out of checkFSEntry into new method
-conConf->requestPath: Don't rely on method sideeffect (i.e. removing/adding '/')
-appendFileName result for checkFSEntry also used for filterFile now
-getFiles: Some error return statements didn't close the directory
Changed "#if NGX_PCRE" to if(hasRegex) (hasRegex in header)
