[tinyPy] Add methods to seek to time and to query current picture fla…

…gs to the Python interface

setCurrentPts(double) in pyAdm expects exact time as argument, seeks to the
last keyframe before the given time otherwise.

Flags returned by getCurrentFlags() in pyEditor are a bitwise OR of values
defined in avidemux_core/ADM_coreImage/include/ADM_imageFlags.h.
