Support 7.2

Drop support for HHVM, add support for 7.2 -> Nightly - thanks to @svpernova09

2.0.0

• update to version 2 of phergie/phergie-irc-bot-react
• Update license year
• Update readme composer example version

1.3.1

• Fixed Composer version requirements such that bot 1.2 and related dependencies are used (@elazar)

1.3.0

• parser >= 1.6 is now required as Plugin is dependent on a fix for an issue related to command arguments (@Renegade334)
• When authentication is successful, a 'nickserv.identified' event is now emitted to be used by other plugins, such as AutoJoin to avoid race conditions (@PSchwisow)
• When issuing an IDENTIFY command to NickServ, the bot's nick is no longer included in order to maintain compatibility with the most networks possible, as some don't support identifying for a nick you aren't presently using, such as Rizon (@Renegade334)
• Configuration options have been added for messages triggering authentication-related events to maximize potential compatibility with various IRC networks (@Renegade334)
• Ghosting support has been improved and potential behavioral conflicts with the AltNick plugin have been resolved (@Renegade334)
• AltNick has been added as a suggestion to composer.json and documentation on using it together with the NickServ plugin has been added to the README (@Renegade334)
• The most current versions of PHPUnit 4.x and Phake 2.x available will now be used (@Renegade334)
• Travis CI testing configuration now includes PHP 7 (@PSchwisow)
• Legacy @license docblock tags inconsistent with the actual license were updated (@Renegade334)

1.2.0

• Fixed a fatal error encountered when the requested nickname is in use (see #2)
• Made the expected message for authentication requests less specific to have the plugin work on more networks (see #4)
