HalfCraft 0.6.0-dev.5+1b18809c4

HalfCraft 0.6.0-dev.5+1b18809c4, built from 1b18809.

Changes since v0.5.0:

• fix: make tidy accepts the message hook reading its MSG out of an LPARAM, which is how windows hands it over (1b18809)
• feat: half-life's close captions go to minecraft while its hud is up: speech into its chat as ' line' in the speaker's colour, the server naming who says it, sounds into its subtitles, and minecraft's show subtitles option turns them on (kStrCaption, kMcSubtitles) (fixes #26) (2cc8cd1)
• feat: half-life's key hints and pickup history show as minecraft toasts while its hud is up: hints name minecraft's keys from its own bindings and source's own by their physical key, pickups stack ammo per type (kStrHint, kStrPickup) (refs #26) (f268afa)
• fix: a half-life weapon moved through the creative inventory stays where it's put down: the server follows the creative cursor it never sees from the slots the creative inventory sets, instead of putting the weapon back and taking the copy on the hotbar (fixes #30) (0995e39)
• fix: minecraft's text fields get what windows types for the player's keyboard layout (WM_CHAR through a unicode message hook) instead of us qwerty characters made up from keys (refs #31) (82053cc)
