Demo Build v1.20

This build includes many bug and dialog improvements, as well as an mprovement to the shipyard user interface.

-- Added significantly more dialog with certain characters

-- Added an additional small screen in the shipyard to show the number of modules currently in inventory when changing modules, as well as the price to fix salvaged modules (when relevant)

-- Fixed a rare issue where changing which key fired a weapon in the ship yard would fail to work

-- Changed default zoom in some levels to make it clearer what's going on (in the Samos system for example)

-- Fixed bug where a specific ship engine might not render correctly

-- Refined enemy AI to improve dodging behavior

-- Fixed a rare bug where enemy ships could get stuck on obstacles

-- Fixed an issue where the UI was showing incorrect buttons in some circumstances

-- adjusted audio volume of ship yard sound effects to make them less obtrusive

-- changed prices on early ship frames to rebalance

-- Fixed an issue where clearing in-flight dialog near planets behaved inconsistently

-- Fixed a rare bug where a specific quest would not complete if there were still enemies alive in the system.
