done for cpp/markdown/python filters on search function

also added wrapped functionality for Python
then checked all python samples, removed ord() and 0xFF anding  - no longer needed -

CV_EXPORTS_W int waitKey(int delay = 0);
/** @brief Waits for a pressed key and returns the corresponding char value (ASCII) assigned.
The function waitChar waits for a key event infinitely (when \f$\texttt{delay}\leq 0\f$ ) or for delay
milliseconds, when it is positive. It returns the ASCII code of the pressed key as a char value. If no key was pressed before
the specified time has elapsed, -1 (most systems) or 255 (if char == unsigned char) is returned depending on the system available.
@note
There is a minor issue for `char == unsigned char systems`. Return value or timeout could be mixed up with value of valid `'\0xFF'` symbol.
However this is an extremely rare usecase, and is thus ignored for the moment.
@note
The function only works if there is at least one HighGUI window created and the window is active.
If there are several HighGUI windows, any of them can be active.
