leper 74c420f658 GUI code cleanup. Fixes #3354.
Lots of code style fixes:
 * type [*&]varname -> type[*&] varname
 * else
   if (...)
   ->
   else if (...)
 * Spaces around some ops.
 * i++ -> ++i.
 * switch-case style fixes.
 * Indentation fixes.
 * Removing some commented out code.
 * include header sorting
 * Changed multiple pointer var declarations to be one per line.
 * Removed strange spaces in some places.
 * Changed some include header guards to be consistent with the rest of
the codebase.
 * Use UNUSED() instead of UNUSED2().

Some small code fixes:
 * Using .find() instead of .count() == 0.
 * !.empty() instead of .size() == 0.
 * Range-based for loops.
 * Making some member functions const by small changes.
   * Adds GetScrollBarPos(idx) const for this.
 * Using early returns/continues in some places.
 * Uses size_t for some loops in CList and COList.
 * Removes unused heading element (not attribute) from COList.
 * Use ENSURE in one case where some custom code did something similar.
 * Made some parameters const ptrs/refs.
 * Change removal loop in GUItext.cpp to erase-unique.
 * Made some static things const.
 * Allow iterating over children of IGUIObject with range-based for
loops by
   exposing begin() and end() (rename from ChildrenIt{Begin,End}()) and
use it.

Comments:
 * Comment COList.
 * Update a few comments.
 * Remove useless or duplicated comments.

This was SVN commit r16931.
