clean up db schema install scripts

[stopfstedt]

database/install/ilios_tables.sql is a mess.

TODO:

• convert tabs to white space
• indent everything properly (4 spaces per indentation level) and align the beginning of each SQL statement with the left margin.
• lose the following statements and fragments:
  • SET auto_increment=1
  • SET character_set_client = utf8;
  • any table comments ( NOT the doc blocks above each CREATE TABLE statement, just the COMMENT='...' on the table itself)
• apply proper quotes to table collation, table engine, default charset etc values.
• add DROP TABLE IF EXISTS statements before each CREATE TABLE statement where missing.
• remove any obsolete commented out code.
