[TYPO3-mvc] RFC: join view helper

[Tomas Majer]

Hi

Nice idea with join!

Before Fluid i used Smarty a I like funcions like: 
{$smarty.foreach.foo.iteration} or {$smarty.foreach.foo.first} etc.

i didnt find this in fluid, so i write helpers like for.first, 
for.notFirst, for.index.

example:

<f:for each="{values}" as="item">
	<ext:for.first each="{values}"> # </ext:for.first>
	<ext:for.index each="{values}" />.{item}
	<ext:for.notlast each="{values}">, </ext:for.notlast>
</f:for>

and output:

# 1.apple, 2.bannana
