Review request for KDE Frameworks and Christoph Feck.


Repository: kiconthemes


Description
-------

At the moment we're playing Battleship to see if an icon is present in a subdirectory. This means that we are checking on every directory if there's an icon that matches the size with a said name on every request.

This can be seen easily with strace:
```
$ strace kwrite |& grep ENOENT | wc -l
6212
```
After the patch: 
```
$ strace kwrite |& grep ENOENT | wc -l
1993
```
We reduce these accesses to let QDir keep the list of files inside the directory (that was already being generated at some point, it just was being discarded).


Diffs
-----

  src/kicontheme.cpp 0996054 

Diff: https://git.reviewboard.kde.org/r/127236/diff/


Testing
-------

Builds, tests still pass, applications start noticeably faster.


Thanks,

Aleix Pol Gonzalez
