This is "shortdesc" in the Lua descriptor

This flushes the dialog (updates it at the UI level) after a Lua
function return.

After the next commit, you'll have to flush a dialog in order to
update it immediately on the screen.
Flush sends an update signal to the UI dialog provider.

PushCommand takes now a new parameter: b_unique. If set, do not push
this command twice in the command queue.

When the input changes (next track, ...), every capable extension
will execute the function "input_changed"

Also remove setting item here as preparsed, as if it has meta, that should
have been done allready somewhere else. Preparsing is controlled by
auto-preparse -variable (no idea where it can be changed), and should work ok.

input_item: compress two functions into one and rename "Add" into "Post" for clarity and consistency

input_item: Remove input_item_AddSubItem2 and send subitem_added event from input_item_node_AppendNode().

This means that we don't need input_item_AddSubItem if there is an input_item_node_Append*().
input_item_AddSubItem now send the subitem_tree_added event as well.

Based on a patch by Adrien Maglo.

Fix memleak. Return E_GENERIC instead of displaying an error message.
