Loading replays progress bar

[Asuna Yuuki Nagato]

Steps to recreate:


Replay->Load Replay
Click 'OK' in Replay msgbox
Select a .zplay file and click 'OK' in the Load Replay (.zplay) window
Player window freezes for several seconds


There should be some kind of feedback that the player is trying to load the replay and it hasn't just frozen.

This loop in load_replay is what is taking so long:



while (util::portable_get_line(file, line))
