Summary0004819: Fix warnings about uninitialized members in debug build
DescriptionSomewhere in 2.06 I enabled warnings about members of game entities not being initialized after spawning (debug build only). However, I only fixed some of these warnings. They still spam hard in the game console.

It's time to go through these warnings and add some initialization for the members.
TagsNo tags attached.

Fixed typeinfo generator in svn rev 7526.

Now it's time to fix the warnings.

Fixed one more issue in memory debugging in svn rev 7528.

The warnings fixed in svn rev 7529 and 7530.

Note: 64-bit version of memory debugging is hopeless, because there are many 8-byte variables, which are aligned up 8-byte boundary. So there are tons of 4-byte padding chunks in classes. All of them are reported as uninitialized.

Just use 32-bit build =)

One more change in svn rev 7564.

I have made the unitialized members check about 50% less effective on 64-bit mode: now it only checks even 4-byte words, odd 4-byte words are skipped because they produce huge number of false positives due to padding before pointers. As a result, all false positives on 64-bit mode are gone: now you should not see any warnings about uninitialized members in 64-bit mode.

This does not affect 32-bit mode: full check is done there.
BTW, I think the same false positives due to padding may still happen, e.g.:
  struct {
    int num;
    double value;
But luckily it does not happen =)
