Growl notifications: Fix attempts to pass std::string instead of const char*

This is required on OS X due to the recent return type changes for the
gettext functions.
Xcode project: switch to using the new boost filesystem code

This includes adding a new library (libboost_localew.dylib; with
libboost_filesystemw.dylib already having been added a few days ago),
so a new version of the Mac compile package is needed for compiling.
Release notes: Add comment about new Xcode compile package requirement
Xcode project file: fix user data directory name

It was accidentally set to ~/Library/Application Support/Wesnoth_1.13
in commit 3d906be.
Changelog: Add comment about new Xcode compile package requirement
Changelog: fix version number
LoW 03: fix coordinates for Urudin appearing at scenario start

These had not been adjusted yet after the map dimensions were changed.
LoW 03: fix coordinates for redestroying village at map change
Spanish translation update
LoW 03: fix two issues with fog

Because the side numbers were changed, fog was cleared for the wrong
side in single player.  This resulted in fog not being cleared at all
for side 3 (bug #22880), and in fog not being cleared when Kalenz first
arrives (time over event), but at the beginning of his turn.
fixup cmakelists, they weren't adding the new libraries

campaignd: Emit debug messages when writing configuration to disk
campaignd: Write config to disk even if the clock is running backwards
campaignd: Fix abs() value truncation warning on clang 3.5
campaignd: Use a POSIX monotonic clock for scheduling config commits

Only available on Linux and probably some BSD systems. For other systems
we issue a #warning and use time() instead (which will cause the
compiler to quit with -Werror, but that's the whole point).
