Generation of default string values is not properly quoted.

[eakoli]

When a column has a default value of type string, the generated sql is incorrect. The string is output as a literal, as opposed to a string.

e.g.

Table "example" {
   "id" integer [pk, not null]
   "value" varchar(255) [not null, default: 'something']
}

Will generate the following sql:

CREATE TABLE "example" (
  "id" integer PRIMARY KEY NOT NULL,
  "value" varchar NOT NULL DEFAULT something
)

Where it should quote something as

- "value" varchar NOT NULL DEFAULT something
+ "value" varchar NOT NULL DEFAULT 'something'

This seems to work correctly when outputting the DBML from the models, which has extra checks to test for string values and encode them correctly.

Thank you for raising and fixing this!
