Removed SQLite migration directory

Corrected the MapSqlStatementsReader::getStatements() method so that it throws an exception if the schema corresponding to a version does not exist

Reverted the renaming of the INDEX TEMP_T_F_I_B_ARCHIVE_FILE_ID_I, will be changed in the version 1.1 of the schema

All indexes have now the same names, cta-catalogue-schema-verify now checks for user created indexes

Added a class SchemaChecker that has the responsiblity of checking :
- the schema against the .sql defined in the SCHEMA_VERSION/xxx_catalogue_schema.sql
- the presence of PARALLEL tables in ORACLE (not implemented yet)

A directory is created regarding the version of the catalogue, the xxx_catalogue_schema.sql is inserted in it at each modification of the schema by the user

Where to store the CASTOR legacy data will hopefully be decided in the future.
