(svn r3680) Fix some magic numbers which got damaged in r1768
-Fix: Correctly restore the roadside after roadworks are finished

(svn r3679) -Fix: [OSX] fixed warning introduced in r3670 about permission denied in G5_detector.c when compiling without having Makefile.config

(svn r3678) - NewGRF Codechange: remove redundant braces and temporary variables.

(svn r3677) Remove the FindLandscapeHeightByTile()s from the default AI.
The corresponding TileInfos look like global variables at the first glance, but always get written to before reading in each function they are used in.

(svn r3676) -Change: [OSX] changed info about package to how to install the game
the package is long gone and people don't read a doc about a missing package when they don't expect to find one
the doc is called install even though it's not a real install and have nothing to do with make install. People just read it the first time they see it when it's called install ;)

(svn r3675) -Fix: [OSX] made the default gcc names for building universal binaries into the newest gcc for each target instead of hardcoding it for 4.0.0

(svn r3674) -Feature: [OSX] Added support for tripple binaries (binaries optimised for G3, G5 and i686)
G4 have no problems using G3 code while G5 can, but really benefit from getting their own optimised code (Apple: G5 is not just a fast G4)
Also changed FAT_BINARY to UNIVERSAL_BINARY since Apple removed most (all?) references to fat binaries on their homepage two days after I added FAT_BINARY

(svn r3673) -Codechange: [OSX] changed the makefile to autodetect if it compiles on G5 and then adds flags to optimise for G5
This will not interfere with crosscompiling or universal binaries

(svn r3672) -Fix: [makefile] fixed bug where some settings where overwritten with the default ones when MAKEFILE_VERSION was changed

(svn r3671) -Code cleanup: fixed style and removed commented out code in video/cocoa_v.m
