Suggestion: Add toggle for 12 / 24 hour format

[pavenarius]

I noticed in the codebase in REFlexFunctions.lua that you are coding US locale timestamps to adhere to 12 hour formats, with the AM / PM designation. However, due to the font size I am using in my setup, I was never able to see the full date, since it overflows the cell and uses a ... notation, so the actual date never shows up, just the time portion. I changed it to use the EU date format, which I prefer anyway.

I would suggest adding a toggle to allow users to change this format, so that people with setups with a larger default font will be able to see the full date.

Alternatively, you could make the columns resizable, or perhaps even the entire frame resizable, so users can set the columns to whatever width they choose, but I recognize this is almost certainly way more work.

Kind regards.
