Exercise Search Improvements

Tonight on Bearly Fit... I have mostly been doing some small search improvements.

When i'm doing a workout, I find myself doing some of the same exercises and it got annoying having to search for them time and time again.

To improve this, I've now made it so the 5 most recently used exercises appear at the top.

And as quality of life additions - I've made it so all exercises now show the last date they were used AND your search criteria is highlighted when searching.

I've also laid the ground work for favourites, improved filtering and sorting but that will all come at a later release :)

Thanks for reading
