Use open_utf8_file_in for opening files in the IDE. (Fix bug #2874)
File system.ml seemed like a better choice than util.ml for sharing the
code, but it was bringing a bunch of useless dependencies to the IDE.
There are presumably several other tools that would benefit from using
open_utf8_file_in instead of open_in, e.g. coqdoc.
