/*
This function allows the following kinds of bets to be made:
Absolute bet
============
bet 14k, bet 50m66, bet 100k
Relative bet
============
These bets are calculated relative to the current bet. The '+' symbol adds
a certain number of percent to the current bet. The default is 25, so
with a current bet of 1000, bet + gives 1250, bet +50 gives 1500 etc.
Please note that the number must follow exactly after the +, without any
spaces!
The '*' or 'x' bet multiplies the current bet by the number specified,
defaulting to 2. If the current bet is 1000, bet x gives 2000, bet x10
gives 10,000 etc.

/*
util function, converts an 'advanced' ASCII-number-string into a number.
Used by parsebet() but could also be used by do_give or do_wimpy.
Advanced strings can contain 'k' (or 'K') and 'm' ('M') in them, not just
numbers. The letters multiply whatever is left of them by 1,000 and
1,000,000 respectively. Example:
14k = 14 * 1,000 = 14,000
23m = 23 * 1,000,0000 = 23,000,000
If any digits follow the 'k' or 'm', the are also added, but the number
which they are multiplied is divided by ten, each time we get one left. This
is best illustrated in an example :)
14k42 = 14 * 1000 + 14 * 100 + 2 * 10 = 14420
Of course, it only pays off to use that notation when you can skip many 0's.
There is not much point in writing 66k666 instead of 66666, except maybe
when you want to make sure that you get 66,666.
More than 3 (in case of 'k') or 6 ('m') digits after 'k'/'m' are automatically
disregarded. Example:
14k1234 = 14,123
If the number contains any other characters than digits, 'k' or 'm', the
function returns 0. It also returns 0 if 'k' or 'm' appear more than
once.
