Allow '-' and '_'

[klibansky]

I am wonderring why you disallow '-' and '_' characters on line 261 since these are perfectly normal characters for file name.
I took them out to suit my needs.

Hello,

Are you using the .js or .dzi that is generated by the package?

I plan to not make the output configurable and therefore the naming less strict for the XML .dzi file. The filename is also used as part of a javascript callback in the .js and needs to be validated.

After doing some digging this morning I can allow '_' and '$' in the javascript function name and checking all possible incorrect names is a 11,236 character long regex: http://stackoverflow.com/questions/2008279/validate-a-javascript-function-name

Thanks.

Hi Jeremy,
I think you got me wrong. You are check the file and folder names for there characters.

[jeremytubbs]

The file and folder names are set by the image filename if they are not explicitly sent.

Example:

  // folder, file are optional and will default to filename
  $response = $deepzoom->makeTiles('KISS.jpg');

Response:

{
  status: "ok",
  data: {
    JSONP: "KISS/KISS.js",
    DZI: "KISS/KISS.dzi",
    _files: "KISS/KISS_files"
  },
  message: "Everything is okay!"
}

Therefore, I am checking the filename for characters that would invalidate the JSONP. I am working on a fix... You are correct that I don't need the same restrictions for the folder name.

Thanks again.
