added basic, incomplete compress/uncompress implementation

[clemos]

to be completed...

I believe there's a problem described in #42 with this.

[ncannasse]

please remove the traces :)
@nadako not sure which problem, if the API is correctly respected. Of course, it will be nice to have progressive (un)compress support as well

[nadako]

@ncannasse the problem of these implementations overshadowing ones in std, so macros don't work.

[clemos]

I just removed the traces.
Honestly, I would definitely implement the rest of the API in both PHP and JS, if only it had some documentation and / or unit tests...

copyright year should be 2015 😛

@nadako ah right, macros. But that can be addressed by merging haxe/std/neko/_std/haxe/zip implementation into it (with #if neko)

[nadako]

yeah but that's not good for obvious reasons of code duplication and maintainance, so I'd really like to see some "proper" solution for that

[ncannasse]

@nadako see HaxeFoundation/haxe#4249

[nadako]

As @Simn pointed out, we could try placing these files in js/_std/haxe/zip and see if it works.

This seems obsolete after #160 (plus there's merge conflicts).
