[Opensource] hsql no cache tables

[Larry Hamel]

fyi, just checked in:

Up through version expresso 5.1, HSQL database tables were created just like other tables. However, looking forward to  HSQL updates,                 a special case was added to create "cached" HSQL tables  sometime after expresso 5.1.
 (Cached HSQL tables are written to the  .data file in binary format, instead of appearing as plain text in the .script file.)  This 'cached' change has been reversed because 1) we have  reverted to hsql 1.6.1,                     2) text files are more easily viewed and manipulated  3)  the cached files may have  been the cause of the mysterious "already opened by  another process" errors.  If you already have a DB created by previous copies,  you'll need to delete  it and start again.
