(svn r11936) -Fix: 'BRIDGE_TOO_LOW_FOR_TERRAIN'-check was wrong for steep slopes.

(svn r11935) -Fix (r11875)[FS#1672]: autosend aircraft to hangar for replacement check inverted the check for autorenew
Now it triggers when renew setting is on and only if it's on
Note: aircraft already enroute to hangars due to this bug will still go there. They will only head there once though

(svn r11934) -Codechange: add persistent random data for river and canal tiles.

(svn r11932) -Codechange: Forgot two occurences of widget enumification

(svn r11931) -Codechange: enumify the widgets numbers. Give breathing room on the case switches too...

(svn r11930) -Codechange: a bit of code style application

(svn r11929) -Fix (r9981)[FS#1624]: [autoreplace] fixed a case where a single headed locomotive caused an assert when being replaced to a dualheaded one
This triggered if the player had enough money to replace and refit one of them but not enough to refit the last one as well

(svn r11928) -Fix (r6393): [autoreplace] autoreplace could refit train engines to the wrong cargo type if the old engine had no cargo capacity and the new one had
Now autoreplace will always look at the wagons to figure out what to replace to (as originally intended)

(svn r11927) -Fix (r11926): unable to place canals in game
