Adopt PSR-4 autoloading standard

[dregad]

Currently, inclusion of source files required prior to instantiating new classes is managed manually in several places in the code.

The library needs to be refactored to follow an industry standard for autoloading supported by Composer.

@dregad How's this issue?
Can you make public that branch you wrote of? Perhaps we can help :)

@antoniopaisfernandes This is kind of low priority, and due to lack of time to spare for ADOdb these days, I have not made any progress towards this. You can have a look at @gohanman's proposed approach in #317, but at this time I'm not yet certain it will be merged as-is.

Anyway, thanks for the offer to help. I'll let you know if needed.

@dregad Are you still interested for this issue. A lot of work would be needed to do this. And I am quite interested to help. I think it should be more feasable to do with small steps. Do you think you could be available for some code review for some small PR ?
