Simple-ddl-parser

Minor Fixes
1. Removed debug print

Improvements
1. Added support for several ALTER statements (ADD, DROP, RENAME, etc) - https://github.com/xnuinside/simple-ddl-parser/issues/215
In 'alter' output added several keys:
1. 'dropped_columns' - to store information about columns that was in table, but after dropped by alter
2. 'renamed_columns' - to store information about columns that was renamed
3. 'modified_columns' - to track alter column changes for defaults, datetype, etc. Argument stores previous columns states.

Fixes
1. Include source column names in FOREIGN KEY references. Fix for: https://github.com/xnuinside/simple-ddl-parser/issues/196
2. ALTER statement now will be parsed correctly if names & schemas written differently in `create table` statement and alter.
For example, if in create table you use quotes like "schema_name"."table_name", but in alter was schema_name.table_name - previously it didn't work, but now parser understand that it is the same table.
