ambiguity with != and /= when cv24 is enabled

[scarf005]

cv24 makes /= look same as !=. while it looks great on haskell project, it might be confusing since those two renders exactly same. here's some approaches:

• change /= operator to use different glyph, like that of https://github.com/i-tu/Hasklig
• a way to disable != (cv25?)

not in standard library, however some external libraries define them as it's a valid function name in Haskell
