v0.1.1-beta

• Fixed issue where templates of same name but different path were overriding each other in main template cache.
• Made sure byte code stored in memory in InMemoryJavaFileManager is cleared when no longer required.
• Removed caching of Reader objects from PebbleDefaultLoader which was causing more harm than good. This can be added back later if it is deemed necessary.
• Completely changed how operators are compiled into Java due to a bunch of bugs regarding operand types.
• Changed the behaviour of the == operator and added the equals operator as an alias.
• Extensions can now provide custom functions.
• Added source, min, and max functions.
• The setting, cacheTemplates, now defaults to true.
• Renamed the main entry points into the main Engine from “loadTemplate/render” to “compile/evaluate”.
• Added i18n extension (disabled by default) and a default locale setting on the main pebble engine. The extension adds one new function: message()
• Small performance improvements when looking up variable attributes.
