Beta Release v0.10.0

• Fixed: Buttons will no longer have a shadow if they are disabled
• Fixed: Export button wasn't locked when transfers were started
• Fixed: Only transition box-shadow on form-control and buttons
  When form-controls were invalid, a background image with a cross would be animated in from left to right
• New: Added a bit of margin to log button, cancel button and transfers because it's not longer added in transition
• New: Added --noreleasecheck so imapsync won't say there's a new version
• Optimization: Removed margin from transitions because it caused lag
• Optimization: Reduced number of messages displayed in output
• Optimization: Added brackets in all useEffects
