Improving KDE's Plasma Performance

Due to KDE's Plasma extensive use of the hard disk for Plasmoids and other activities, and thinking about KDE's performance on mobile device, Aaron Seigo has been working to make the library consume less memory. He has achieved at least partial success in this effort.

"The result was that the copy test (100k copies and deletions) went from ~2700ms to ~37ms, while 100k copies, file lookups and deletions went from ~3900ms to ~40ms. All while the memory footprint shrunk. Unfortunately, this isn't really backportable to libplasma1 as the changes that were required to achieve this were significant. These changes were on top of previous changes made in the refactoring of Package and PackageStructure which drew the data "closer" to Package and cut out a lot of collection creation and copying.
