RELEASE-1.0.0b5

Console, some overall improvements, including BREAKING CHANGES.

* The PHAR file is now also a console. When installed, the console is available from the executable "roscon".
* __BREAKING CHANGES:__
    - Response::getArgument() is renamed to Response::getProperty() (Note: Request::getArgument() is still valid). Response::getArgument() is left issuing an E_USER_DEPRECATED notice, and will be removed in a later release.
    - Message::getAllArguments() is removed in favor of IteratorAggregate implementation that returns an ArrayObject. For most intents and purposes, you should be able to just search&replace "->getAllArguments()" with an empty string (that will implicitly call getIterator()). If you require the arguments as a "real" array, you can replace "->getAllArguments()" with "->getIterator()->getArrayCopy()".
    - Message::\_\_invoke() without arguments is now a shortcut for getTag() instead of getting all arguments.
    - Util::changeMenu() is now renamed to Util::setMenu() and always returns the Util object itself.
    - ResponseCollection::\_\_invoke() without arguments (or NULL) is now a shortcut for getting the iterator of the current response, instead of for seeking to the last response. Replace "()" with "(-1)" or "->end()" to achieve the old effect.
    - ResponseCollection::getLast() is removed. To get the last response, you can instead use array access (or offsetGet()) with "-1" as the offset. Or simply search&replace "->getLast()" with "->offsetGet(-1)".
    - ResponseCollection::getArgumentMap() is renamed to ResponseCollection::getPropertyMap().
    - All Query::ACTION\_\* constants are renamed to Query::OP\_\*, and shortened (GREATHER_THAN is now GT, etc.).
* New Util methods:
    - getMenu() (serves the same purpose as previously Util::changeMenu() with an emptry string)
    - getAll()
    - count() (makes Util an implementation of Countable, reports the number of items at the current menu)
    - prepareScript()
    - appendScript()
* Message now implements Countable, reporting the number of arguments (on COUNTER_NORMAL) or words (on COUNT_RECURSIVE).
* Util::get() now uses RouterOS' "get" command, unless it returns an empty !done response (as it does for RouterOS versions prior to 6.0), in which case it automatically fallbacks to a print with a query.
* Util::escapeValue() and Util::parseValue() now support associative arrays (introduced in RouterOS 6.2).
* Util::escapeValue() now correctly converts DateTime objects to DateInterval objects relative to UNIX epoch time in UTC. Previously, the current time zone was used instead of UTC.
* Util::add() and Util::set()/Util::edit() now support flags as values with a numeric key.
* Util::filePutContents() now behaves correctly when the underlying Client has enabled streaming of responses and/or when the contents is in a stream. 
* Responses in ResponseCollection can now be getted or seeked to a value relative from the end by supplying a negative offset.
* ResponseCollection can now be searched by argument values, if you first designate an argument name with the new ResponseCollection::setIndex() method.
* ResponseCollection can now produce a sorted response collection based on user defined criteria using the new ResponseCollection::orderBy() method.
* Util::find() now always returns a comma separated list when used without arguments (as opposed to ";" separated, in more recent RouterOS versions).
* Response receiving now resets if an empty sentence is received, instead of throwing an exception.
* New Communicator::seekableStreamLength() method, used internally by Util::filePutContents().
* Doc fixes (Notably: Clarified the acceptability of seekable streams as argument values, which has been present for a long time, but never documented).
* CS fixes.
