Migrate from 1.4.9 to 2.0

• Since 2.0.0 block's name should be scalar:

{block $name}{/block} {* invalid! *}
{block 'name'}{/block} {* valid *}

• Constant Fenom::DENY_INLINE_FUNCS replaced by Fenom::DENY_NATIVE_FUNCS:

$fenom->setOptions(Fenom::DENY_INLINE_FUNCS); // invalid!
$fenom->setOptions(Fenom::DENY_NATIVE_FUNCS); // valid

• Tag {raw} doesn't support block tags, use the tag option :raw:

{raw:block_function}...{/block} {* invalid! *}
{block_function:raw}...{/block} {* valid *}
