three syntax-sugar proposals

[Bulat Ziganshin]

Hello haskell-prime,

1. allow to use '_' in number literals. its used in Ruby and i found
that this makes long number literals much more readable. for example

maxint = 2_147_483_648

2. allow to use string literals in patterns as head of matched list:

optionValue ("kb"++n) = read n * 2^10
optionValue ("mb"++n) = read n * 2^20

this syntax already used in Erlang

3. writing kinds is very rare task, but i still don't like to count
number of stars in something like '* -> * -> * -> *'. i think that
representing this as '****' will be more readable
