Farmlist improvements and fixes

+Troops while adding/editing a raid lists are now inside of a table,
this is a graphic enhancement
+Reduced the X and Y textboxes size while adding/editing a raid list
+Fixed a bug that didn't permit to add a raid list
+Fixed a bug that did permit to insert spies in raid lists
+The farmlists graphic is now more clear, "Add raid" and "Start raid"
are now two general buttons, instead of having two buttons for raid list
+"Select all" checkbox, will select all raid without refreshing the page
(through JS)
+Moved the function "getDistance" to Database.php
+Removed a lot of redundant code from crop_finder.php
+Removed rams, catapults, chiefs and settlers from the raid list,
because the first three can't even loot resources
+Removed trooplist2.tpl because of a more general unique template file
(trooplist.tpl)
+Some minor improvements and bug fixing

IMPORTANT NOTE: if you don't want to reinstal the whole server, you can
simply run this little query (where "s1_" is the prefix of your server):

ALTER TABLE `s1_raidlist` DROP `t7`, DROP `t8`, DROP `t9`, DROP `t10`;
