* Clean the user's display name on update.
The user's display name should always be clean (see for example
functions/src/create-user.ts). However, change-user-info.ts does not
enforce this, thus potentially allowing a malicious user to change their
name to something that doesn't satisfy the rules for clean display
names.
Note: this cannot happen currently because all callers (in profile.tsx)
clean the name. However, doing it here is good defense in depth
(similar to how the userName is cleaned).
* Update display name max length to 30
* Add a script to hunt down too-long display names
* Make util.isProd a function

This is a hacky patch for a problem that runs more deeply: the use of
floating-point for Mana calculations, along with the associated rounding
errors.
Consider the following example:
```typescript
const balance = 1000
const bet = 5.6e-14
const newBalance = balance - bet
if (newBalance == balance) {
alert(`I placed a bet of ${bet} without changing my balance.`)
}
```
This will actually print a message, because floating-point numbers can
only represent so many digits, and thus we get 1000.0 rather than
999.99999999999994.
This is a purely theoretical attack at this point; nobody could create
enough pico-bets to actually affect their balance using this technique.
However, I believe is worth ensuring a minimum bet amount, and might
prevent other problems such as the UI showing messages like "User Foo
bought M0 of YES", which could confuse users.
For a more definite solution, we would probably need to change some
computation to integers, where addition is always commutative and
value-preserving. This is similar to what most financial software does
(e.g., Bitcoin uses 1 Satoshi = 0.00000001 BTC as their unit).
