Added text functionality to pictures.

The method I am using to merge the text into the original bitmap leaves
the text blurry afterward. This needs to be done better.

Need to add options to change text color/style/font/size
Fixed issue with blurry text.

The problem wasn't with merging the bitmaps. Turns out the compression
to a byte stream was causing it. I changed the compression to use png
instead of jpg and now it's good!
Added ability to change text color.

Using one of the premade examples in the SDK -> ColorPickerDialog.java
