QGSpider - a game cheater for Linux

This patch 'solves for me' three following problems:
1. lvalue cast (happens with gcc 3.4 and above)
2. search results not being shown, despite being found (happens with qt 4.2
- not sure, maybe only happens for me)
3. NR_syscalls not defined (happens at kernel 2.6.17 and above, I think -
now it's defined only for kernel compilation) - this one is not a fix, only
a hack to make it work, a proper fix would require a rewrite of the way
qgspider identifies syscalls - as it only intercepts 3, it should not
create a null-filled array for all calls, just, don't know, maybe a
switch/case
