When a number command is expected but other is issued (/orange for example)

[lenara]

This bug happens when the user chooses a flavor to invest on, the list with suggested investment amounts is displayed, but instead of choosing an amount the used sends again a flavor command or any other command for that matter.

The crash is quite bad and will also crash again on restart unless the user types a value command.

this bug affects other sections when the user has to select a command with a number (list from gift, creative, etc...)
if the user types another command instead, things will happen.
in the market, the bad loop crash mentioned in previous comment
in the creative/gift , if the user types /orange it will "switch" to the market bets. it will only crash once, not loop-crash

Fixed for speculation market. Used handy isNaN() function.
