Add force param

[kuzmany]

This just add force param to

{feeditems count="30" force="1"}

This force display items in order in RSS (by default use date)

@kuzmany Thanks for your PR. Personally I think "force" a bit misleading / vague. I think an attribute "order" is better with the the options:

• rss
• date

What do you think?

[kuzmany]

@ChrisRAoW I understand you, but we already use it in production, then It make BC for use. I think it's great improvement and bugfix for some users. It's up to you decide to close it or merge it.

@kuzmany What do you mean with "BC for use"?

[ChrisRAoW]

@kuzmany Ah "backwards compatible"....I understand. Will give it another look.
