Tomáš Votruba 726cf4cddf Added EasyCodingStandard + lots of code fixes (#156)
* travis: move coveralls here, decouple from package

* composer: use PSR4

* phpunit: simpler config

* travis: add ecs run

* composer: add ecs dev

* use standard vendor/bin directory for dependency bins, confuses with local bins and require gitignore handling

* ecs: add PSR2

* [cs] PSR2 spacing fixes

* [cs] PSR2 class name fix

* [cs] PHP7 fixes - return semicolon spaces, old rand functions, typehints

* [cs] fix less strict typehints

* fix typehints to make tests pass

* ecs: ignore typehint-less elements

* [cs] standardize arrays

* [cs] standardize docblock, remove unused comments

* [cs] use self where possible

* [cs] sort class elements, from public to private

* [cs] do not use yoda (found less yoda-cases, than non-yoda)

* space

* [cs] do not assign in condition

* [cs] use namespace imports if possible

* [cs] use ::class over strings

* [cs] fix defaults for arrays properties, properties and constants single spacing

* cleanup ecs comments

* [cs] use item per line in multi-items array

* missing line

* misc

* rebase
