Added back codestyle checks via Drone

[jatitoam]

• It uses latest joomla/coding-standards for checking
• Added checks via Drone
• Fixed Codeception to v.2.3.7 as it's the latest supported (cc @puneet0191)

Important note: better squash this PR while merging, there was a good deal of tests while dealing with it

Enjoy !

@jatitoam Any reason for Travis over our Drone? :-)

[jatitoam]

Just used to it. Is Drone a preference now?

[yvesh]

@jatitoam as we got rid of travis totally in joomla 4 yes.. (We had and still have too many services)

[jatitoam]

True and good idea to merge them. Can you please help me enable Drone for this repo so I can send a config file for it instead?

[yvesh]

@jatitoam okay done. Thanks!

[jatitoam]

Ok it's switched @yvesh :)
However I'm not sure what the Drone URL is to see the output so I tested it in a personal Drone in the meantime.

Can you please check and confirm? (and merge if you agree of course)

Also remember to require the Drone check for develop and master pushes once it's enabled

[jatitoam]

Heya :) just a friendly reminder, is it realistic to say that Drone will be enabled (and my code merged) if I solve conflicts?

[rdeutz]

I activated drone for this repo, so if you solve the conflicts it should work

[jatitoam]

Ok thanks, it's ready for merge now

[puneet0191]

Thank you @jatitoam

[puneet0191]

@rdeutz can we merge this?

[puneet0191]

Thank you @jatitoam
