Align stuctures for 64-bit platforms

[GermanAizek]

@Atoptool,
Smaller size structure or class, higher chance putting into cpu cache, changes require checking using yours benchmark, I haven't figured out how to run bench in your project yet.

Most processors are already 64 bit, so the change won't make it any worse.

Affected structs:

• extraparam 120 -> 112 bytes
• vertval 136 -> 128 bytes
• pridef 48 -> 40 bytes
• syscap 64 -> 56 bytes
