Internals: Added LastActiveId, LastActiveIdTimer. (#1537)

Examples: Visual Studio projects: Disabled extraneous function-level check in Release build.

Added extraneous initialization to NULL. (#1527).

Merge of minor left-overs from private work branch to reduce drifts. Should be functionally a no-op.

Fixed non-popup child windows not honoring the HiddenFrames flag (can't see a reason). Docking relies on this.

Internals: Settings api tweaks

DragDrop: Removed IsDragDropActive() (introduced a few days ago, revert 06bea36) as our use case doesn't need it anymore. Will add it if there is a real need.

Demo: Minor tweaks.

Demo: Improved Selectable() examples. (#1528)

Columns: Clear offsets data when columns count changed. (#1525)

Internals: Renamed ImGuiSimpleColumns to ImGuiMenuColumns to avoid confusion. Reduced internal buffer size (we only use 3 slots).

Updated copyright date for 2018

Casing tweaks + clarify license copyright (simpler/safer?) (#1346)

Renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.

Internals: NextWindow: Renamed, moved functions to member.

Internals: NextWindow: Using ImGuiCond for consistency.

Internals: refactored g.SetNextWindow fields into g.NextWindow. structure (so it can be more easily transported/copied)

Fixed Android clang warning.

Merge pull request #1529 from unprompted/master ...

Fix a memory leak of ImGuiColumnsSet's Columns vector.  ImVector doesn't call destructors.
