Subject: Custom labels (#2027)

* First draft of custom tags

https://github.com/FreshRSS/FreshRSS/issues/928
https://github.com/FreshRSS/FreshRSS/issues/1367

* SMALLINT to BIGINT for id_entry

And uppercase SQL types

* Fix layout for unreads

* Start UI menu

* Change menu order

* Clean database helpers

https://github.com/FreshRSS/FreshRSS/pull/2027#discussion_r217971535

* Travis rules do not understand PostgreSQL constants

Grrr

* Tag controller + UI

* Add column attributes to tags

* Use only favicon for now, for label

* Fix styling for different themes

* Constant for maximum InnoDB index length in Unicode

https://github.com/FreshRSS/FreshRSS/pull/2027#discussion_r219052200
(I would have personnally prefered keeping the readability of a real
value instead of a constant, in this case of many SQL fields)

* Use FreshRSS_Factory::createCategoryDao

* Add view of all articles containing any tag

* Fix search in tags

* Mark as read tags

* Partial auto-update unread tags

* More auto update tag unreads

* Add tag deletion

* Do not purge tagged articles

* Minor comment

* Fix SQLite and UI bug

* Google Reader API support for user tags

Add SQL check that tag names must be distinct from category names

* whitespace

* Add missing API for EasyRSS

* Compatibility SQLite

Problematic parentheses

* Add SQL DISTINCT for cases with multiple tags

* Fix for PostgreSQL

PostgreSQL needs some additional type hint to avoid "could not determine
data type of parameter $1"
