Fix "clean" to remove the entire "www" directory to prevent build problems with using dirty data.
(The "media" directories were being left behind).

Fix misspelling of "Croatian" (was missing the 'r')

Merge in changes from trunk, mostly the translation to Slovene.

Document that the translator for Slovene is Jelko Urbančič.

Add Jelko Urbančič to the credits (translator into Slovene)

Tag the source code used to build version 7.6.0.

Add perf numbers from 7.5.0 and 7.6.0

Update with the results from the 7.6.0 test pass (no regressions found)

Update the value of :ID_SETPENSIZE to match changes in mainframe.cpp.

Corrected the wording of a chagne for 7.6.0
The translation table menu items were only removed from Croatian builds, not Slovene builds, because the Slovene build did not exist before 7.6.0.
