Update .travis.yml

add a report of the actual precise version info of the compiler
add notes about print being replaced in lua
Big Animals MAI: bug fix for units sometimes not attacking
Lurkers MAI: bug fix for attack error when lurker runs into ambush

If the lurker move is interrupted by an ambush, the attack action
previously sometimes caused an error, because the lurker might not get
to its target.
Fixed Morogor's location being described all wrong.
SotBE S6: reduce randomness of unit types unloading from galleons

This is done to keep the difficulty of the scenario more consistent. We
now always unload one level 2 unit and two level 1 units (assuming that
at least 3 landing hexes are available).
add wesnoth.show_lua_console, as a debugging aide

This allows some sort of "drop into debug" mode for lua if your
script detects an error.

We could consider to actually add an "option to attach debugger"
as an error handling mechanism, but it might be complicated
because of wesnoth exceptions which must go through lua and be
treated as lua errors, and we cannot handle two exceptions at once
obviously, so the lua interpreter is probably not safe to run that
way in general. Anyways this commit does not do that.
add a header required by CB/MinGw
CB build system update

Add an active orb icon for the Display -> Colors options page

Made it myself by tweaking the existing orb.
use fast function pointers for scaling algorithm selection

The first implementation used boost function pointers but these
are much slower for many reasons. This commit refactors the system
to use traditional C-style function pointers, which is all that is
actually needed.
Merge branch 'master' of https://github.com/wesnoth/wesnoth
vc build update
replace typedef'ed type uintmax_t by its long form unsigned long long

It seems this type is not yet available in MSVC9, only in later versions.
add and use constructor (instead of assignment)

This fixes a MSVC warning about "cannot instantiate
customcodecvt_do_conversion_writer".
make included boost headers more specific

This works around a compile problem in MSVC9.
(some conflict in those boost headers ?)
fix warning about unreferenced variable
fix MSVC warning about data loss
fix MSVC warning about comparison signed <-> unsigned
