[502] Limit / truncate the number of files shown on tree view.
Created by: cirosantilli
At 100,000 files it does 502 or Firefox times out.
At 10,000, it responds but Firefox dies while viewing it.
GitHub truncates at 1000, probably a good size.

The funny thing is, GitHub dies on the commit view because of the huge diff, but GiLab truncates it properly (after a long loading time): https://gitlab.com/cirosantilli/test-diff-many-files/commit/9ab0f32010eb98d667c73a3b46bc6485d513e098#
