Adding a static function for current locale to the tag

[leonidlezner]

The current locale is not get by app()->getLocale() but by a static function. With this change it is possible to implement custom logic of getting the locale inside of custom Tag. It can also be used to set the locale to a fixed value to "deactivate" the translation functionality.

Thank you for this. Could you give an example of a situation where this functionality is needed?

I've added the tag functionality to the edit page of groups, which can be created by users. They can enter the tags, but they are saved with the current locale (can be set to German or English for each user). So when German users save the tags, English user don't see them. And vice versa. Those tags should contain the same information for all UI languages. By setting the return value of getLocale() to 'en' I can force the tag information to be saved for the same locale (now they are kind of language independent).

This looks good. Could you also update the docs explaining this functionality with a good, clear example?

I've added the example, hope it's clear enough :)

I'll polish it a bit myself, thank you for this!
