Collections Abstraction library

This release, combined with the release of doctrine/annotations v1.6.1, fixes an issue where parsing annotations was not possible for classes within doctrine/collections.

Specifically, v1.6.0 introduced Psalm-specific annotations such as (for example) @template and @template-implements, which were both incorrectly recognized as @template.

@template has therefore been removed, and instead we use the prefixed @psalm-template, which is no longer parsed by doctrine/collections v1.6.1

• 186: Use @psalm-template annotation to avoid clashes thanks to @muglug

This release bumps the minimum required PHP version to 7.1.3.

Following improvements were introduced:

• ArrayCollection#filter() now allows filtering by key, value or both.
• When using the ClosureExpressionVisitor over objects with a defined accessor and property, the accessor is prioritised.
• Updated testing tools and coding standards, autoloading, which also led to marginal performance improvements
• Introduced generic type docblock declarations from psalm, which should allow users to declare /** @var Collection<KeyType, ValueType> */ in their code, and leverage the type propagation deriving from that.
