added alter table statements for adding and removing indexes when maps are loaded. THis way i avoid mysql's limit of 64 indexes per table. the toptimes and own times can now be displayed very quickly ingame. ONly exception is if dev/ze2/ze play the same map because mapStart and MapEnd add and remove the indexes. So if dev/ze/ or ze2/ze play the same map then the first server leaving the map will delete the index again

//a mysql table can max have 64 keys attached to it without recompiling. Therefore dropping and attaching binary tree index on the given map start, map end,
//PluginStart Database connection and PluginEnd.
//Adding and removing indexes should be pretty cheap so creating/removing them for only the specific map should be ok
//also check that racezones actually exist before making a binary tree index
//also handles if the column ends with just mapname or with mapnameS1, mapnameS2 etc etc
//its only relevant for sourcemod scripting part, the java backend making rest endpoints uses a cache and does select * statements so it does not need indexing
