Performance issues on reverse engineering for DBs with many files on NEWREVENG command

[shantstepanian]

The NEWREVENG command had performance issues for schemas with large # of files (we had a SQL Server use case with ~23,000 objects).

Upon profiling, looks like the "replaceSnippet" call is very expensive [1]

Worth trying to get a performance test in on this first (we should generate the 23,000 files on the fly, not check them in), and then to analyze and debug the issue)

deploy.bat newreveng -dbType MSSQL -mode SCHEMA -outputPath C:\myinput -username *** -password *** -dbSchema *** -inputPath
