* Implemented "auto-popping" by adding **!** at the end of any symbol.
* Removed all symbols ending with **!** as auto-popping will work instead.
* Improved contrast and readability of the min web site.
* Extended **operator** to support the creation of constructor symbols.
* Now using **dict:http-response** and **dict:http-response** for HTTP requests/responses.
* Now using **dict:timeinfo** for time info.
* Changed **parse-url** to push a **dict:url** on the stack.

### Breaking changes

This release also introduces quite a lot of breaking changes aiming at addressing some language inconsistencies and making the language more stable overall. 

Read this carefully! It is most likely that your code will breal when you upgrade.


* Removed **quote-define** (=) and **quote-bind** (#).
* **define** (:) now auto-quote quotations as well.
* To quickly bind a quotation to a symbol (and essentially create a symbol operator but with no validations or constraints), use the new **lambda** symbol or **^** (alias, sigil).
* Removed **typeclass** and extended **operator** to create type classes as well.
* Renamed **string** and **float** type names (used in operator signatures) to **str** and **flt** respectively.
* Removed **define-sigil**, use **operator** instead.
* Removed **module** and **+** (sigil); use **require** to create modules.
* Removed **call**, **^** (sigil, alias -- reused for **lambda**, see above); use **invoke** to access module/dictionary symbols.
* Removed **set-type** symbol.
* Removed **~** sigil (rarely used).
* Renamed the following symbols:
  * `int` -> `integer`
  * `bool` -> `boolean`
  * `delete` -> `delete-symbol`
  * `defined?` -> `defined-symbol?`
  * `seal` -> `seal-symbol`
  * `sealed?` -> `sealed-symbol?`
  * `unseal` -> `unseal-symbol`
