[Libreoffice] [GSOC][patch] Multiline inputbar

Hello Kohei,

As said I've modified the codebase over Noel's patch and worked on
showing the button up and basic toggling working.  So far the text
window and the container class resizes well base on the button click.
But currently I'd need to work on following things also

1: Setting the proper output area when the toggling happens. I've
tried working on it but was not able to get vertical offset proper
when in multiline mode. So need to look more into its mathematics.

2: As Noel mentioned in, his last mail that I'm setting the height to
TBX_WINDOW_HEIGHT instead it can be more than that. I tried fetching
the current height in ScMultiTextWnd::Resize() and setting the correct
height but I did some wrong implementation and LO was crashing because
of that. So I'd need to look into that too.

3: The third thing is, when the resize happens, the ScInputWindow i.e
toolbox  doesn't resize. The overflow of the child window is hidden
inside ScInputWindow.

So this patch contains a basic button implementations and toggling of
the textbox (resizing it) based on the click. I took time because it
took some time to understand the new codebase which makes this feature
runtime switchable. Please review it as soon as possible and help me
work on the above mentioned things.

Thanks and regards
