[Kst] kdeextragear-2/kst/kst

[George Staikos]

CVS commit by staikos: 

Added "extension" framework to Kst which allows Kst to make use of optional
technology not available in the minimum required KDE version.  Added
KJSEmbed extension, which is only marginally functional right now, and is not
in the build since it needs an autoconf check still.
