Add comparison with other PHP MediaWiki frameworks

[waldyrious]

It would be helpful to compare how to do some simple demo tasks with Wikimate and a couple of the most popular PHP frameworks for the MediaWiki API, as that would allow prospective users to make a more informed decision about whether to pick Wikimate or some other project for their needs, as well as provide some concrete backing to the claim in the README that Wikimate "aims to be very easy to use".

Such a comparison, if comprehensive, might instead live in a central location like https://en.wikipedia.org/wiki/Wikipedia:PHP_bot_framework_table or https://www.mediawiki.org/wiki/API:Client_code/All#PHP, but let's start modest and begin with something tailored to highlight the why's and why-not's of Wikimate itself.

There is already this table: https://en.wikipedia.org/wiki/Wikipedia:PHP_bot_functions (linked from https://en.wikipedia.org/wiki/Help:Creating_a_bot#PHP) but it has essentially not been updated since its creation in 2010.

That's pretty cool! Hopefully it's something that doesn't require a lot of knowledge of each framework's internals to update. Perhaps that page should be moved to mediawiki.org (and btw, I just noticed that https://en.wikipedia.org/wiki/Wikipedia:PHP_bot_framework_table should also be merged into the nearly identical https://www.mediawiki.org/wiki/Manual:Creating_a_bot#PHP).
