Replace small Tomster icons with Ember's 'e' icon

[dipil-saud]

Resolves #871

These are the different areas where the 'e' icon is added:

• 'Inspect Ember Component' context menu
• 'Webpage is running Ember' Indicator icons

Also adds a higher quality icon for the firefox devloper tab.

Thanks so much for the PR! This looks awesome 😄

I see we are still using Tomster in some spots. @locks @teddyzeenny what do you guys think about removing Tomster entirely and just going with the "e" logo everywhere? Might feel a little more uniform, but I am open to whatever.

@rwwagner90 I think that is likely a good idea. While I love Tomster, it is too busy visually at small sizes.

Thanks for the feedback @locks 👍

@dipil-saud with this in mind, can you please remove the remaining Tomster icons and replace with the same "e" logo?

[RobbieTheWagner]

@dipil-saud can you please replace all tomster icons with the e icon? Then this should be good to merge 👍

[RobbieTheWagner]

@dipil-saud we could also potentially replace the others after the fact, if you do not have bandwidth to make the change. Just let me know!

[dipil-saud]

@rwwagner90 I'll make the changes. Was AFW for a while.
