Various fixes and improvements:

• Hover mode on Jetpack! Pressing 'J' will toggle between normal and hover modes. In hover mode, you can just move around with up/down/left/right, perfect for building tall structures without needing to make a giant scaffold next to it
• When picking up materials, the selected item in the hotbar will no longer change to the most recent gathered material
• Tools in the HUD toolbar are now directly clickable to swap to them
• BUGFIX: Switch pixels are now mineable into their loose form
• BUGFIX: fixed the issue in Upgrades where the Hammer had incorrect tooltips showing for the cost
• BUGFIX: escape key no longer lets you break out of the messages in the spaceship (which would break questline)
