just a few code clean up...
works:
1. add "palette_item_frame" shape for tweaking palette item frame
appearnce in the future
2. fix the issue that cannot load the palette color from local db
correctly
3. tweak the palette item appearance a little bit to prepare for saving
thumbnail into local db
Works:
1. add a new field into PaletteData db table:
 - ImageUrl
2. add two new parametes into PaletteData class:
 - imageUrl
 - updated
3. In PaletteDataSource, implement the parse work to get the data from
db and convert it to PaletteData instance
works:
1. remove the capture view's landscape layout xml temporarily as it
causes app crash
2. add convertBitmapToByteArray() method into BitmapUtils so that we
could convert and save the thumb into local db
3. update palette item view to display the updated time
add handling logic (empty for now) to catch and handle when the option
button in pallete item is clicked
works:
1. add a new PaletteItemOptionsDialogFragment used to show options for
PaletteItem
2. add its handling logic (empty for now) into the main activity
