- [X] Removes some string allocations (e.g. split) - [X] Optimizes some collections - [X] Converts insensitive to extension methods of built-ins. - [X] Adds ordinal (case sensitive) string helpers - [X] Fixes conditionals for in-game commands so they use Ordinal comparisons. - [X] Replaces ToLower.Contains with InsensitiveContains - [X] Adds ValueStringBuilder - [X] Implements ValueStringBuilder in a few places where it makes sense - [X] Removes the redundant Wrap function and replaces it with an optimized version - [X] Fixes list conversions in Utility Closes #351 Bumps release version
