Added {exp:stash:extend} tag for injecting stash embeds into variables abd blocks.
Updated readme, and comment
* Slice is now correctly applied to lists after sort/order but before filtering.
* List_count() now supports the same filtering parameters as get_list.
* When using the `prefix="x"` parameter with get_list, only prefixed varaibles will now be parsed by default, unless `require_prefix="n"`
* Removed dependency on iconv for transliteration of embed file names to ascii, because it is unreliable across environments; now filenames must be alphanumeric, - or _
* {stash:nocache} now works *inside* snippets that are inside stash embeds, and this behaviour is recursive.
* Fixed #80
Updated README
Added unprefix parameter for protecting common variables in tags wrapped by stash:set, stash:parse. Deprecated no_results_prefix for stash:set. Prefix parameter for stash:set, stash:cache, stash:parse, stash:embed and stash:set_list can now be used for {[prefix]:nocache} tags, so that escaped regions are linked to their parent tag. Improvements to nocache handling.
Added unprefix parameter for stash:cache
Added {exp:stash:join_lists} tag for creating unions of one or more lists. Added `prefix` as a permitted parameter for stash:cache and stash:parse tags. Add `compress` parameter to set/get for remving whitespace between html tags
