Curl: Use TLS instead of SSLv3.

SSLv3 has known security issues.
composer.lock: Fix Texy dependency version (2.2.0 -> 2.2).

It looks like Texy deleted the "v2.2.0" tag from their repo.  Not cool.
Move "fix-style" to "support/check-style-phpcsfixer" and update rules.

- Show fixes instead of actually performing them.
- Use rule blacklist instead of whitelist, so we get new rules as the
  tool is updated.
Add PHP CodeSniffer script and config.
Code style fixes.
composer.json: Upgrade ApiGen dep to 2.8.2, which fixes its Nette dependency.

ApiGen 2.8.1's composer.json dependency on Nette was too permissive,
which breaks things.  ApiGen 2.8.2 locks it down more.
tests: Upgrade to PHPUnit 4.0
ChangeLog: Update for 1.1.4 release.
