Lots of little changes, plus two bigger ones:

Fix a tokenization error with sections containing only the number zero.

Yay PHP!

 * Add section filter support

 * Add more flexible cache options
 * A nested partials whitespace bugfix
 * Add ArrayAccess context lookup support
 * Some lambda section optimizations and smarter cache defaults

 * Allow stream URIs in Filesystem Loader (thanks @mlebrun!)
 * Fix bonus indents in lambda sections inside indented partials

 * Improve tokenizer and parser performance and memory usage. Wheee!

 * Allow passing entity flags for htmlspecialchars() (thanks @pinterface)
 * Fix filesystem loader to work with stream wrappers (thanks @mlebrun)

 * Fix tokenizing when using `mbstring.func_overload`

 * Fix default value for Mustache_Engine::render context passthrough (thanks @jimbojsb!)

Add a 'strict_callables' option to Mustache_Engine

…m inside a callback).

 * Don't ask closures about their methods or properties.
 * Allow extending FilesystemLoader (protected instead of private methods).
 * Allow "empty" filesystem loader file extension.
 * Add a "cache_file_mode" option to set cache file permissions.
 * Add filters.
