0.29.3 - QOL & mining drones polishing

Hi all!

This update brings a lot of quality of life improvements to the game. I've spent a lot of time testing, whacking bugs, painting over ugly UI and asking code to behave well :D

Changes:

• All drone docks now require a drone to be build

• Description of fuel production tech was updated to include info about unlocking dock ports

• Drones are now more common in visitors offer

• Rebalanced HP of each drone

• Drone HP is now saveable HP

• Interaction, when multiple objects are hovered at once, was updated - select what is currently seen on top, then rotate through underlying elements (previously, the first element selected was random)

• Don't show pipe in hovered objects list, when not in pipe overlay mode

• In Guest Dock show when visitor will appear

• Easier pipeline laying

• Added a quest to pay back some loan

• Dropped object is highlighted when clicked

• Default UI panels placement cleaned up (they are no longer all over the place)

• Changed pipe connection removal to middle mouse button

• Improvements to camera movement - pan to mouse when scrolling

• Improvements to camera movement - restore move camera by right mouse button

• changed pipe overview logo

• When demolishing is done - drop resources that were contained in device + were used to build device

• Small improvements to UI & lang

Bugs:

• Tech tree scrolling/dragging nightmare solved

• Graphene production fixed - it can be produced in Chemical Plant

• Device build cost is no longer serialized - it might change for some devices it was cached before

• Fix for dropped items not being collected sometimes

• Starting screen langs fixed

• Resolved a bug causing error when selecting devices to build while still in cancel build mode

Big thanks to tjtravel who found many of the bugs fixed in this and upcoming updates :)
