Pass viewdatadictionary in blockgrid and blocklist html extensions. Add index to block.

[SofusMunch]

The current GetBlockListHtml and GetBlockGridHtml extensions don't allow passing viewdatadictionary to the partials. I use nested blocklists, for example in a slider blockgrid component:

Since I need to pass some settings from the gridcomponent to the listcomponents I use viewdatadictionary. Unfortunately I can't use the GetBlockListHtml extension.

Also since I need to set the first slide with an "active" class, I've changed the default blocklist view to add an index value:

I haven't looked at the source code, but if possible I think it would be a good addition if a block had an index property.

Hi @SofusMunch.

I think you are right, that this would be a nice improvement. I'll add it to up-for-grabs for now.
