games/endless-sky: update to endless-sky-0.9.14

Pkgsrc changes:

* Update the makefile to handle subdirectories in the cource code.
* Update the ImageBuffer patch to load images correctly.

Announcement:

0.9.14 Polish release

This is a "stable" release, focusing on bug fixes and polishing
the recent v0.9.13 release. New changes include the following

* Numerous typo fixes
* Fixes to how several missions are offered to the player
* Better suggestions of possibly incomplete conditions in some
  missions' "visit" dialogues
* Differentiation between two Remnant engines' reversing capabilities
* Certain Navy shipyards now stock the Dropship
* Ships that have no specified "drag" attribute default to 100,
  rather than causing crashes
* Weaponry that alters the ship's status conditions (e.g. ionization)
  now respects the required minimum value of 0
* The "interrupt fast-forward" preference defaults to off

Some minor improvements were added to help support plugin authors
and content creators:

* Quarg planets now have regional attributes to enable better
  targeting via missions
* Missions that fail to be instantiated print more informative
  messages in the error file
* Large numbers of missing image frames no longer pollute the error
  file

0.9.13: Unstable release

This is an unstable release, containing big changes that may
introduce new bugs.

Breaking changes:

* Starting conditions no longer automatically override the game's
  default start. Plugins that use a "start" node will need to make
  changes to restore the previous behavior.

Major new changes include the following:

* 70+ new missions in human and alien space
* Outfits can now be stored on planets, without needing to install
  them on a parked ship
* An overhaul of almost all human outfit images
* Players can now choose their starting scenario
* Spaceport news messages no longer include portraits by default
* Better handling for missing content definitions (e.g. from plugin
  removal)

Several features have been added to the game engine, for use by
plugins and other content creators. These include:

* Dynamic stopover selection will consider planets without spaceports
* A number of new outfit and weapon attributes, offering shield/hull
  multipliers, weapon aiming & firing overrides, percentage-based
  damage, and additional damage mitigation
* Arbitrary angles for hardpoints, engine flares, and fighter bays
* NPCs' objectives can now include provocation or capture
* Mission NPCs can be conditionally spawned or removed without
  needing to change the player's active missions
* Missions can react differently when the player aborts a mission,
  and when the player fails a mission
* Missions can give ships to the player
* Systems may generate environmental hazards, control the range at
  which ships enter, and be hidden on the map

Add Endless Sky, a side-scrolling space trading game.

(Its ancestry clearly includes Elite, though I couldn't say how in any
detail.)

Alas, it does not run on my NetBSD because of opengl version issues,
but it should run on Linux and MacOS.

Be careful, it can be quite a timesuck :-)
