(svn r11110) -Fix (r11107): somebody forgot to update project files ;)

(svn r11109) -Fix r11106: it is silly to use a std::list for something that is cleary a std::vector (less memory ;) WHOHO!)

(svn r11108) -Fix (r11107): somebody forgot to add some file ;) Spoils the fun of the previous cryptic message though.

(svn r11107) -Feature: some tool so one can still build tunnels under rails (and other structures) when the owner of the structure built it on foundations and if you have enough "empty" space ofcourse. One could use the tool for some other construction needs too. Patch by frosch.

(svn r11106) -Add: added .tar support; you can pack all files in your data/ dir in how ever many .tar files you like, keeping the dir-structure equal to the unpacked version, and OpenTTD can handle them just like the files were unpacked
-Note: useful for GRF-packs and 32bpp PNGs. Don't forget to keep the dir-structure alive for 32bpp PNGs!
-Note: file-loading-order: search-paths, .tar-files in the order found on disk (can be anything at all, don't depend on it.. use 'openttd -d1' to see which order they are added)

(svn r11105) -Codechange [FS#1223]: add some support for tuning of the bounding boxes for some special cases (like tunnels and bridges). Patch by frosch.

(svn r11104) -Fix: bounding boxes also overlap when the min of a bounding box is equal to the max of another bounding box. Patch by frosch.

(svn r11103) -Codechange: remove pointless comparison as it can never ever be true (unless you've got at least 3 bit errors and then you're screwed anyway). Patch by frosch.

(svn r11102) -Codechange: remove some pointless addition+substractions. Patch by frosch.

(svn r11101) -Fix r11099: the check: file_pos == 0, no longer works; adjust the check with file_slot. This solves the ? sprites with autorail (nice catch Progman)
