Improve copy of start/end segment button

[AlecRust]

Current Problem

Ever since using this (excellent) extension the labelling of the main "Segment Starts Now" button has irked me 🙂

Button labels should typically start with a verb i.e. the "action" that will be performed - "Start" in this case. Right now in both "states" of the button, the label starts with a noun - "Segment" in this case.

User shouldn't need to read somewhere in the middle of the button to determine the "state" the button is in.

Proposed Solution

• Segment Starts Now -> Start Segment Now
• Segment Ends Now -> End Segment Now

One for a separate PR, but due to the importance of these start/stop buttons I feel like they could benefit from being full width, and include an icon for each state to further differentiate.

Looks good!

Todo for me: trigger an update in crowdin instead of replacement before merging
