Currently, the expFile::dumpDatabase(), expFile::parseDatabase() & expFile::restoreDatabase() all work with the entire database/eql file at once (unless the table selection is small) which may exhaust available memory (esp. on ecommerce sites). We need to fix this by:

• Change the file($filename) calls in parseDatabase() & restoreDatabase() to use fgets($filename) and handle the .eql file line by line rather than all at once.
• Change the dumpDatabase to incrementally output/write the .eql file instead of creating an variable of the entire .eql file and then echoing/writing it.
