[TYPO3-ect] Introducing the controller as a register

[Elmar Hinz]

Hi developers,

based on the vision of TS configurable actions, I introduce the controller
as a register. This is easy, because the controller is an SPL object
itself, so there is a register already build in. I use "TS notation" to
show it:

submitAction {
 ...
 model = tx_my_model
 model {
   do.1 = load
   do.1.1 = keyOfTotalResultCount   // first parameter
   go.next = ...
 }
 ...
 view = tx_my_viewWithResultBrowser
 view {
   do.1 = makeResultBrowser
   do.1.1 = keyOfTotalResultCount  // first parameter
   go.next = ...
 }
...
}

The regular content data is transported inside THE ARRAY of the SPL objects.
Somtimes we need to transport some additional information along the SPL
chain, for example the number of the total result count for the result
browser. 

Such additional data kann be registered into the array of the controller by
use of a key. Here we use the key "keyOfTotalResultCount".

The model registers the value. The view reads the register in a later step
using the same key.
