Bug 494978

SUMMARY
Using forward slashes when naming a note, notebook, and folder results in multiple directories being made (ie. creating a note named test/example/demonstration results in a folder named demonstration within another folder named example, within the main note directory being named test. This also ends up confusing KleverNotes as doing this causes it cycle between names for the affected directory.

STEPS TO REPRODUCE
1. Create a note/notebook/folder
2. Use forward slashes in name
3. Open storage directory in Dolphin and see folders made
4. Open and close KleverNotes to see name of the affected thing randomly change (might happen only once)

OBSERVED RESULT
Multiple unnecessary directories are created, KleverNotes confuses name of the affected thing 
Also can't name the notes/notebooks/folders with forward slashes.
EXPECTED RESULT
KleverNotes should not allow this to happen and either inform the user or give the user a prompt to substitute the forward slashes for back slashes. (Similar to how Dolphin does it but without letting the user do it anyway as it serves no purpose in KleverNotes)
