Uploader.setValidExtensions() doesn't update IFileInput's accept attribute properly

[GoogleCodeExporter]

What steps will reproduce the problem?
1. setup Uploader with default IFileInput.FileInputType.BROWSER_INPUT
2. call Uploader.setValidExtensions("csv");
2. open Uploader UI in the browser
3. check "Choose Files"form <input> attributes 

Expected: <input type="file".... accept=".csv"/>

Actual: <input type="file"... accept=""/>

What version of the product are you using? gwtUpload-1.0.0

On what operating system? Ubuntu 12.10

The problem is marked with **PROBLEM**:

public void setValidExtensions(String... extensions) {
    this.validExtensions = new ArrayList<String>();
    validExtensionsMsg = "";
    if (extensions == null || extensions.length == 0) {
      return;
    }
    List<String> v = new ArrayList<String>();
    String accept = "";
    for (String ext : extensions) {
      if (ext == null) {
        continue;
      }
      if (ext.contains("/")) {
        accept += (accept.isEmpty() ? "" : ",") + ext;
        continue;
      }
      if (!ext.startsWith(".")) ext = "." + ext;
      validExtensionsMsg += (validExtensionsMsg.isEmpty() ? "" : ",") + ext;
      ext = ext.replaceAll("\\.", "\\\\.");
      ext = ".+" + ext;
      validExtensions.add(ext);
    }

    ** PROBLEM: notice "accept" var only gets appended if ext.contains("/" ) above, so it'll be empty in the happy path **
    fileInput.setAccept(accept);
  }
