i-bem: more modular way for inheritance from base block (close #428)

@veged @narqo please, take a look

I guess this will bring more misunderstandings as with bem-events from #394. Don't you think we should have one right way to define blocks instead of three ways*?

modules.define('i-bem__dom', function(provide, BEMDOM) {

BEMDOM.decl('ablock', {});
provide(BEMDOM);

});

modules.define('i-bem__dom', function(provide, BEMDOM) {

BEMDOM.decl({ block : 'ablock', modName : 'm1', modVal : 'v1' }, {});
provide(BEMDOM);

});

vs

modules.define({ block : 'ablock' }, function(provide) {

provide({});

});

modules.define({ block : 'ablock', modName : 'm1', modVal : 'v1' }, function(provide) {

provide({});

});

vs

modules.define('ablock', ['i-bem__dom'], function(provide, BEMDOM) {

provide(BEMDOM.decl('ablock', {}));

});

modules.define('ablock' function(provide, Ablock) {

provide(Ablock.decl({ modName : 'm1', modVal : 'v1' }, {}));

});

`or maybe I haven't caught the idea, sorry

I guess we have to support and recommend only the one clear true way for each case. The way which introduces minimal patching to modules.define for BEMDOM-blocks.

Inheritance of block from another one

modules.define('ablock', ['i-bem__dom'], function(provide, BEMDOM) {

provide(BEMDOM.decl(this.name, {}));

});

modules.define('bblock', ['i-bem__dom', 'ablock'], function(provide, BEMDOM, ABlock) {

provide(BEMDOM.decl({ block : this.name, baseBlock : ABlock ));

});

Inheritance of block from another level

modules.define('ablock', ['i-bem__dom'], function(provide, BEMDOM) {

provide(BEMDOM.decl(this.name, {}));

});

modules.define('ablock', function(provide, ABlock) {

provide(ABlock.decl({}));

});

Adding modifier to existing block

modules.define('ablock', ['i-bem__dom'], function(provide, BEMDOM) {

provide(BEMDOM.decl(this.name, {}));

});

modules.define('ablock', function(provide, ABlock) {

provide(ABlock.decl({ modName : 'm1', modVal : 'v1' }, {}));

});

Well, it looks nice
