Added magnifying glass icon to the StyledHorizontalMenuFilter

[MaksymKarunos]

• Added a new icon of Magnifying Glass to the src/components/Icons (the icon is scraped from the original search icon located in the header, for some reasons it was not in the folder with all .svg icons).
• Updated StyledHorizontalMenuFilter with the icon so it can be easily reused.

I'm pretty sure there is a magnifying glass graphic somewhere already. It's being used for the submit button on the Explorer page for example.

Yeah looks like you can use the ActionSearch built-in icon here:

web/src/components/Explorer/index.jsx

Line 267 in e7db47f

icon={!this.state.loading ? <ActionSearch /> : null}

Thank you so much! I am sorry I am still getting used to the project!
Making changes now!
