[TIMOB-1778] Android: Add Method to TiBlob for Retrieving Underlying File

From the developer-facing API perspective, the right thing to do here would be to return a FileProxy. However, TiBlob lives in the titanium project (non-module), which to date has no references to our modules.

What do you think is the right way to handle this? Return a TiFile, which lacks API documentation?

Maybe we should just documenting returning a path that can be passed to the filesystem API to get a file object. Would that suffice?

.nativePath it is.

Setting back to "new" while not working on it. Still have no idea how to get a file path from a content url, and sick of looking for it for now.

Bear with me while I make a test case - coming soon

QA: here is an app.js you can use to test this. I'm morphing it into a drillbit test as well, to be committed soon:

   Titanium.UI.setBackgroundColor('#000');
   var win = Titanium.UI.createWindow({  
       title:'Test',
       backgroundColor:'#fff',
       exitOnClose: true
   });
   win.open()
   
   var console = Ti.UI.createLabel({
       left:0, right:0, top: 0, height: 400,
       backgroundColor: 'black', color: 'white',
       font: {fontSize: 12}, verticalAlign: 'top'
   });
   win.add(console);
   
   function w(s){
       if (console.text && console.text.length > 0) {
           console.text = console.text+ '\n\n* ' + s;
       } else {
           console.text = '* ' + s;
       }
   }
   
   var filename = 'blobtest';
   var testphrase = 'Revenge of the Blob';
   
   w('getting file with path segments ' + Ti.Filesystem.applicationDataDirectory + ', ' + filename);
   
   var file = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, filename);
   
   if (file.exists()) {
       w('file exists.  deleting it.');
       file.deleteFile();
   } else {
       w('file did not exist -- no need to delete it.');
   }
   
   w('putting text "' + testphrase + '" into file');
   
   file.write(testphrase);
   
   w('getting blob based on file');
   
   var blob = file.read();
   
   w('destroying original file variable instance to test getting it back via blob');
   
   file = null;
   
   var path = blob.nativePath;
   
   w("blob says file's path is " + path);
   w("getting new file instance based on that path");
   file = Ti.Filesystem.getFile(path);
   if (file.exists()) {
       w("Good - file is said to exist when I get it from that path.");
       w("Will read contents and see if they match the phrase we put in earlier.");
       var readphrase = file.read().text;
       w('Read this text: "' + readphrase + '"');
       if (testphrase === readphrase) {
           w('Yay! The phrases match.  TEST SUCCESSFUL');
       } else {
           w('FAIL!  The phrases do not match.  Something is wrong.');
       }
   } else {
       w("FAIL - file is said to not exist.  Something is wrong.");
   }
