A bug when when extracting from an image with tesseract

[voz]

Error:

< 29 Mar 22:40:41 - error: [App] Error extracting [[ /XXX/Screen Shot 2014-03-06 at 14.43.23.png ]], exec error: Error: Command failed: read_params_file: Can't open Shot

The problem is that the paths are not escaped before calling the tesseract command:

  exec( "tesseract " + filePath + " " + fileTempOutPath + " quiet",

Will submit a pull request fixing the issue.
