* not dropping the cache just because we change themes; this made sense when just plasma-desktop used this or when the apps using Plasma::Theme all used the same theme. this is no longer the case, really, and having applications changing themes randomly kicking the cache out from underneath other apps that may still be using it is undesirable. this does mean that cache files will accumulate. not sure that's a big issue as they don't tend to be large and are in an area marked as "cache" (so ripe for clean-without-care) * cleanups such as getting rid of superfluous use of Plasma:: namespacing in code that is now in libplasma, such as the stylesheeting. (it was from a plasmoid sebas wrote originally, iirc, explaining the historical reason for the explicit namespacing) svn path=/trunk/KDE/kdelibs/; revision=1203345
