This patch adds a feature mentioned in http://wiki.wesnoth.org/EasyCoding,
namely the first one in "Engine related features". To implement this feature, I added the command field in the configuration for the context menu.

This comes as an alternative to https://github.com/wesnoth/wesnoth/pull/246
added to changelog and about.cfg
preferences: Replace "Disable notifications" with "Desktop notifications"

Because inverse-logic options are evil and this was the only one in the
entire Preferences dialog anyway.
preferences: Give the Desktop notifications option a tooltip
Update players changelog for default minimap config changes
Guardian Micro AI: remove translation marks from map labels

These are meant as technical information for UMC authors, not “normal

Display number of random traits with the list, and skip if zero.

where woses would get a list of traits displayed.

add "Defense Capped" col. to terrain table in help page for units

If a unit has a "negative" modifier on one of its terrain defenses,
for the basic terrain defense types that have been discovered and
will be displayed on the current help page, a column will be
generated "Defense Capped" which indicates which terrain types
have the negative modifier. In each row the column contains either
'-' or 'yes'.
add a help topic link from "Defense Cap" col. to terrains section

Added to the topic for that section a brief explanation of mixed
terrains vs basic terrains, "best defense worst movement", and
defense caps.
fix bug in help.cfg wherein list of terrains wasn't generated
Merge branch 'master' of git://github.com/wesnoth/wesnoth
update changelogs
fixup some comments about terrains in help.cfg added earlier
tweak the help page list of traits display, for undead units

If a unit *only* has musthave traits, then we don't count them
and omit the number, just listing 'Traits: ... , ...'. This really
only changes how undead units' traits are displayed. This looks
much better without sacrificing clarity in these cases.
add a "special notes" for defense caps, with a link to explanation

This is better than what it was doing before this commit, which was
putting the link in the text in the table.
remove server compability code for 1.11.12

this causes stderr warnings.
