new default icons for selected default labels + filter counter for overview in drawer

[Rushour0]

Added default label icons
Made a new enum type - DefaultLabels which maps to the respective png files
A new default label can be added in DefaultLabels, with its corresponding png file in assets/icons with the same name as the label

Example :
label: videos
filename: videos.png

Added a class DefaultPaths
The intelli-sense can make it faster to write these paths, than having to remember them.

Example:
normal string path: assets/icons/
with DefaultPaths: DefaultPaths.defaultLabelIcons

The variable can be autocompleted with intellisense and reduces the need to remember the path if the variables are well named
