Benoît Minisini e945a9faa6 [INTERPRETER]
* NEW: Requesting a component interface automatically loads the component 
  now.
* NEW: The Image and Picture functions in the interpreter API were removed.

[GB.DRAW]
* NEW: A new function in the Draw interface to get the size of a picture.
  This function replaces the removed Picture interpreter API.

[GB.IMAGE]
* NEW: This is a new component that manages images in memory. It implements 
  the Image class, can create images of many formats (RGB, RGBA, BGRA...) 
  and convert image data between different formats. This component replaces
  the previous interpreter Image API. All components were ported to this
  new image management system by loading this component automatically.
  Beware that the Image constructor has changed! The transparent property
  has been removed, and there is an optional color argument that is used
  for initializing the image data. Moreover, many classes (Webcam, 
  PdfDocument...) that have an Image property lost their Picture property.
  Now to get a Picture, you must use the Image property and then convert
  the Image to a Picture.

[GB.QT]
* BUG: As now the Image class overrides the one located in gb.image, it 
  must be declared early, at least earlier than the Picture class.

(Daniel Campos <danielcampos@netcourrier.com> ) - All float values has been replace
by double values, as some extra wrong decimals were added in conversions from sql data
types to Gambas data types.

Uses the STL and requires the sqliteclient library. Currently tested with
SQLite 2.8.13. from www.sqlite.org

sqlite is typeless...although in the create you can specify type details (these are
just comments!).  These types have been defined to map to gambas, those not defined
will default to string.

Thanks go to Leo Seib for his SQLiteDataset library ( sqlitedataset.sourceforge.net)
which has been the base for my hacking.

The order for locating database files is:
1) If database is fullpath qualified
2) If Host is specified as a valid path
3) If set, GAMBAS_SQLITE_DBHOME variable
4) Current working directory.

The driver will look for databases in the current working directory unless the environment
variable GAMBAS_SQLITE_DBHOME is set.

There is no concept of users within sqlite.  Access is controlled by file permissions
on the database file. 

Creates database /tmp/sqlite.db by default.  For the gambas-database-manager this will
allow functionality.

Sqlite is not case sensative on table or field names.  The implementation for Gambas is. 

Database :memory: will load only in memory
