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).

* Get answer outcome from comment
* Avoid db call if possible
* Include general comments note in comment emails
* Send market-comment on general comment
* randomString: generate a securely random string.
Also, support lengths > 12 in case that's ever needed.
This is used in at least one case (creating device tokens for users)
where it seems important that the output is unpredictable.
* Try harder to create unique usernames.
The previous version added 16 bits of entropy to the username, which
isn't all that much. Due to the birthday paradox, it would be enough to
create ~256 users with the same prefix to get a collision.
Trying that would probably fail later on, and not create security
issues... but it just seems better to be on the safe side here.
