Fixes

• Fixed a bug where images pasted via clipboard would not save to the folder properly resulting in loss on refresh.
• Fixed a bug where the syntax for pasted images would change from [[Image.png]] to ![Image](link to image file) on save in the markdown storage. Note: These would self correct the next time you make a change in the file.
• Fixed a bug where placeholders where not shown.
• Fixed a bug where an empty todo item would not show the blinking caret.
