Classpath order and init macro execution order for haxelib dependencies

I have two libs: libA and libB.
libA depends on libB. Both have init macros. I'd expect init macros of libB to be executed first, however:
```
$ haxe -lib libA
/home/alex/temp/test/.haxelib/liba/InitA.hx:3: Lib A
/home/alex/temp/test/.haxelib/libb/InitB.hx:3: Lib B
```
I think this should be changed to always execute init macros of dependencies before init macros of dependants.
