Add more fps modes

[Fewnity]

Small pr to add 24, 40 and 50 fps config modes to save bandwidth.

I changed the fps counter too, instead of showing 60 as the maximum framerate, the counter shows stream's target fps. To have 40/40 instead of 40/60 at screen.

can you squash first and third? you can it git rebase -i HEAD~3

this command will open the editor to choice the commit

pick ff8514d ...
s da6c974 ... # swap 2<->3 lines then change mark squash
pick fcbf1e4 ...

after that, git wil reopen the vim for editing the commit message you can drop da6c974's message

then push branch with force git push origin branch -f
