Change name to make Eddy more discoverable

[chayros]

I recently read an article that praised Eddy as tool for ElementaryOS and critized that it was not integrated in the OS.

This kind of reminded me that i had an experience where i knew that a great Deb-Installer exists but i didn't knew the name and i would not expect the average user to make the same effort as me to find it.

It might be a minor thing but i still think it would be useful to use a more descriptive name like "Deb-Installer" in the long run to make it more accessible even if it's just for the search bar, so when you search through installed apps it shows what it actually does and users wouldn't have to click a random app called "Eddy" without knowing what it does.

I think Eddy is a great tool and really useful in the near future for people who want to use ElementaryOS as daily driver.

This is my first issue, if i did something wrong, feel free to point me a way how to do better and thank you for your hard work :)
