Pass an higher amount of memory to asm.js

[makevoid]

The new Geth keys use a bigger kdfparams.n and that requires more memory

I believe this is true from geth 1.4+?

That's the error I get when decrypting a key (via the recover fn):

Cannot enlarge memory arrays in asm.js. Either (1) compile with -s TOTAL_MEMORY=X with X higher than the current value, or (2) set Module.TOTAL_MEMORY before the program runs.

And this is the stacktrace of the abort() Error I get on the deriveKey function:

With the new value of 280MB it works without errors

Thanks!
