CCSM->Put plugin: the "Put to arbitrary viewport" bindings aren't working

[Micheal Hsu]

CCSM--> Put plugin:
set key bindings in "Put to arbitrary viewport" section.

but the key bindings only work once.

this is caused a programming error in put.cpp:

bool PutScreen::toViewport (....)

the function resized the CompOption every time it's called.(this can cause memory leak).
subsequent calls to getIntOptionNamed(..) always return the first "viewport" value instead of of the correct value, which is appended to the tail of the vector.

the correct way is to find the "viewport" option and then set its value.
