Issue title: schemacrawler does not like column name (identifier) quotation with sqlite 
 Issue body: Hi,

really nice tool! Thanks for your work on it.

Here goes:

This sqlite DDL results in output with correct primary key information and markup (bold, italic):
```
PRAGMA foreign_keys = ON;

CREATE TABLE Deal (
  deal_source TEXT NOT NULL,
  deal_id TEXT NOT NULL,
  fo_deal_id TEXT NOT NULL,
  PRIMARY KEY (deal_source, deal_id)
);

CREATE TABLE DealCost (
  deal_source TEXT NOT NULL,
  deal_id TEXT NOT NULL,
  deal_cost_no INTEGER NOT NULL,
  fee_type TEXT NOT NULL,
  PRIMARY KEY (deal_source, deal_id, deal_cost_no),
  FOREIGN KEY (deal_source, deal_id) REFERENCES Deal (deal_source, deal_id)
);

```

htmlx output result:

![unquoted](https://user-images.githubusercontent.com/2393913/27088332-a8419978-5057-11e7-839a-70d96d1093ba.PNG)


...while this does not:

```
PRAGMA foreign_keys = ON;

CREATE TABLE "Deal" (
  "deal_source" TEXT NOT NULL,
  "deal_id" TEXT NOT NULL,
  "fo_deal_id" TEXT NOT NULL,
  PRIMARY KEY ("deal_source", "deal_id")
);

CREATE TABLE "DealCost" (
  "deal_source" TEXT NOT NULL,
  "deal_id" TEXT NOT NULL,
  "deal_cost_no" INTEGER NOT NULL,
  "fee_type" TEXT NOT NULL,
  PRIMARY KEY ("deal_source", "deal_id", "deal_cost_no"),
  FOREIGN KEY ("deal_source", "deal_id") REFERENCES "Deal" ("deal_source", "deal_id")
);
```
htmlx output result:

![quoted](https://user-images.githubusercontent.com/2393913/27088175-3f3ff582-5057-11e7-8558-fcfd5fd31e4b.PNG)

The only difference is the quoting of identifiers, which is more or less recommended to not clash with
sqlite keywords; for me, this also happens as a side effect of using [ponyorm ](https://docs.ponyorm.com/) to create the DB tables i.e. I can't easily switch this off.

The same happens with other diagram output formats (png, svg). 

Some version information: graphviz 2.34.0, sqlite 3.7.17 (yeah I know this is all pretty old but I don't currently have access to more recent versions - corporate environment...)
 Comments: 
 Comment 0: That is a very interesting bug in the SQLite JDBC driver. However, the good news is that I can work around it in the SchemaCrawler code. I will fix it and release a new SchemaCrawler version.
 Comment 1: Please use SchemaCrawler 14.16.02.
