get_value and its use

[tex]

This is inplace element, general version of inplace_textbox and inplace_textarea.

It can replace both of them by simply:

inplace{edit=#textbox{}, view=#span{}},

inplace{edit=#textarea{}, view=#span{}}.

It also supports #image and #dropdown. Any other element can be used as well.
It supports actions connected to edit element.

Example:

body() ->
Span = #span{},
TextBox = #textbox{ id=testBox, actions=[ #validate { validators=[ #is_required { text="Required." } ] } ] },
ListBox = #dropdown{ options = [
#option { text = "Pokus1" },
#option { text = "Pokus2" },
#option { text = "Pokus3" } ]},
Image = #image{ alt="obrazek" },
TextBoxImage = #textbox{ text = Image#image.image },
[
#panel { body=[
#inplace { tag=a, text="Pokus1", view=Span, edit=TextBox },
#inplace { tag=b, text="Pokus2", view=Span, edit=ListBox },
#inplace { tag=c, text="/images/test.jpg", view=Image, edit=TextBoxImage }
]}
].

......iiiiiiinteresting. I really quite like this. We can use this as a replacement for #inplace_textbox and #inplace_textarea in general, changing those other elements to just use this, while opening this up as a more flexible abstration.

I dig it.

Before I merge this, I'd like to play with it a bit, but I like this a lot. Kudos to you.

Cool!

Let me know if you'd like to change something. I personally don't like much the part about getting/generating view and edit element's IDs. I'll rewrite it using the base 'trick' I learnt some time after I created this element.
