Changed wording of non-local-storage message and header message, make delete button smaller

Minor aesthetic fixes in this commit.
Added saving generated image when left clicked

Since apparently right click to save only works in Firefox. Added a library for it too.
Added bootstrap-select to aid in selecting colors, not finished yet

Current status:
-Color dropdowns don't change colors when color is selected
-Dragons can be added and have correct colors in sidebar
Fixed bug where exiting edit w/o editing would cause next add to be edit
Added colored buttons for add/edit dragons

Had to find button via group because bootstrap-select automatically generates it. Now it works!
