players and games csv improvement

Changes I've made
--------------------------

[+] players.csv 
  - separated squads.csv into better machine-processable parts.
  -organized by player name
[+/-]  games.csv 
 - removed all the Windows encoding issues for things like (Carl JÃ¸rgensen  to Carl  Jørgensen), remember to encode things as UTF-8, if you want it to be understood by all Operating Systems. Its still not perfect for the ref names (check this chart for help: http://www.i18nqa.com/debug/utf8-debug.html)
- separated games.csv into better machine-processable parts.
- added the lat/long for every stadium where a match was held.
- organized by game_id
