Migranten-Konversion gibt es nicht mehr.

fix a fall-through in jsonconf causing an error message.
add tests for pool, not working because of missing GIVEITEM on
JSON-configured races (TBD).
Replace RCF_PLAYERRACE with RCF_NPC, it's the less confusing default for tests.
replace RCF_CANSTEAL with RCF_NOSTEAL for less confusing default behavior.
test coverage for can_steal.
add a default message for when no messages are loaded, so that msg_feedback/msg_message doesn't return NULL when XML has not been laoded.
initialize some core stuff before running tests (there probably needs to be more).
refactor setup for economy tests.
rename can_steal->check_steal for consistent naming, check_give->can_give, too.
Simple test for rules.give (there are many more, can_give deserves a test to itself).
The more tests I write, the more I hate the infrastructure for them.
use race::flags|RCF_NOGIVE instead of race::ec_flags|GIVEITEM
None of this has tests, it'd going to be years before a change like this can be made without fear D-:
Revert "use race::flags|RCF_NOGIVE instead of race::ec_flags|GIVEITEM"
E3 Tests (GIVE) did not pass.

This reverts commit 5ec3f5b83aa5b599df8ecec0d8afea1612e173f1.
also read the extended race::ec_flags from JSON configuration.
test giving silver from the pool
if a unit is empty, and not a TEMP, then it is dead and cannot recruit.
This fixes http://bugs.eressea.de/view.php?id=2010
a new method for finding out that a unit died in battle.
turns out, a unit can have 0 people without dying or being a TEMP (GIVE them all away, then RECRUIT more).
print log errors after runnign tests
add a test for the E3 reduced give quota.
foreign units receive only 50% of silver given to them.
