Decrease the size of instaler

[idcarlos]

You can decrease the size of your setup file if you add
this line at the top of your NSIS script

SetCompressor lzma

If you like I can get involved in the development of minor
tweaks of your installer, send me a mail.

lzma is slow. Also lzma usually compresses everything at a
whole and not each file individually. So to decompress,
temporary files have to be created.

I'll try to see which impact the lzma headers have if not
using solid compression.
