[omxplayer] Don't flush queued data on general reset

We were flushing the queue of data to gpu (which can be a number of seconds worth) on a general reset.
However this is generated on inoccuous events like a chapter change in dvd playback.

This results in a few seconds loss of audio, and a temporary audio/video sync error
[UX] consistent playback behavior for music and video
build: make D-Bus configurable
[pvr] use channel path instead of channel name for CFileItem path property
[pvr] sync selected item between pvr windows
fixed: keyboard layout blank and double QWERTY.

There are 3 solutions to this issue

1) @notspiff fix to use a fallback to English with the font13 which is
not what's used elsewhere in skin
https://github.com/notspiff/xbmc-cmake/commit/8ca6d81189acb43d1d136935b5013b5f9ae5410c

2) use the Roboto fonts I was working on and no longer am, but already has
the Hebrew characters added (correctly or incorrectly idk)
http://forum.xbmc.org/showthread.php?tid=150067

3) simple, use English names, since default language is English, users
must have some degree of understanding of that and smart enough to know it.

Since I no longer work on that font , nor speak such languages I was
adding characters for and have no desire to extend it from what is done
atm

This was my solution, both simplest and avoids dealing with niggling issues.

As m_selectedItemPaths is a map we need to check if the corresponding map value is empty instead of the whole map.
