fixes:
- proper upgrade to 1.4.6
- fixed dota parser finding the maps again
- fixed bans/picks
- added versionmm and select_mode fields
- fixed version field to now show dota minor/major version
- seems to basically work with 6.77 too

to update perform in System -> Database -> Import:

alter table {pre}_replays_dota add column replays_dota_versionmm int(8) NOT NULL default 668 after replays_dota_version;
alter table {pre}_replays_dota add column replays_dota_select_mode varchar(2) NOT NULL default 'cm' after replays_dota_versionmm;
