Changed MiniYaml.NodesDict property into a method.

Method is now called ToDictionary.
- Cached a few invocations into locals which should prevent some redundant evaluation.
- Added ToDictionary overloads that take projection functions for the keys and elements, since several callsites were doing a subsequent Linq.ToDictionary call to get this.
Improved efficiency of startup methods.

- ShpReader will copy the input stream into memory just once rather than for every header.
- ShpReader.CopyImageData switched to use Array.Copy since that uses some unsafe magic for speed.
- In ActorInfo, cache a GetType call and prevent needless materialization in PrerequisitesOf.
- In ObjectCreator, cache type and ctor lookups since these are expensive and often repeated.
- Implement IReadOnlyDictionary<T, U> on Cache<T, U> to provide some supplementary functions.
- In TechTree.GatherOwnedPrerequisites, rearrange a Boolean 'and' expression to evaluate expensive functions later in the chain, and use ContainsKey to speed up name check.

Fixed IDisposable implementation and usage.

- Implement IDisposable interface correctly, with sealed classes where possible for simplicity.
- Add using statement around undisposed local variables.
Make map preview generation fast.

- Change Map.LoadMapTiles and Map.LoadResourceTiles to read the whole stream into memory before processing individual bytes. This removes the cost of significant overhead from repeated calls to ReadUInt8/16.
- Remove significant UI jank caused by the map chooser by not including the placeholder widget. The maps render fast enough that it is no longer worthwhile and it was causing a lot of flushes which were the source of the jank.
- Trigger async generation for all maps when the chooser is loaded. This means in practice all previews will be ready by the time the user begins to scroll the selection. Since generation is fast, there is no issue with scrolling straight to the bottom and having to wait for the backlog to clear.
