[5.4] Convert zRangeByScore syntax for PhpRedis

[tillkruss]

This converts Predis':

['WITHSCORES' => true, 'LIMIT' => [$offset, $count]

To PhpRedis:

['withscores' => true, 'limit' => [$offset, $count]

Just a related note: Predis doesn't really care about which casing style is used for command modifiers keywords as it converts them to uppercase internally, so you can pass these as WITHSCORES or withscores or even WiThScORES and it won't make any difference. The use of uppercase-by-default in Predis, in docs or code, is just for consistency with the Redis documentation.

@nrk: Yeah, we use Predis as the standard and just make sure the syntax is converted when PhpRedis is used. What would really help us is a full documentation of all Predis methods and their supported signatures. I noticed that some methods can be called in 2-3 different ways.

Do we actually need this if the case doesn't matter?

[tillkruss]

Yes, Predis doesn't care, PhpRedis does 😐

@tillkruss having proper documentation for Predis would be awesome but unfortunately I don't have enough free time for it and nobody seems motivated enough to submit contributions in this area. I know the test suite shouldn't really be used as a reference, but test units for each command cover all of their supported signatures.

@nrk: Okay, thanks, I'll have a look!
