Description : Text editor for Blitz+.

I dropped this project. It works but I have no use for it at this moment.

; Blue text editor by Crom Design 2004
;
; Blue
;
; Note - The data array can not be accessed directly without using the line pointer function bluelinenum(num)
; This is becourse large text files (1gb) and so on tend to be a bottleneck on the processor while
; editing... (Not implemented yet in this version but will be in later versions unless I find a better method)
;
; Current Implementations :
;Ctrl + Page Down
;Alt+F4
;Data array adjusts to size of text file.
;Mouse press aligns cursor (single/multi line)
;Line numbering (optional and dynamic) / Buffered
;Del
;Commandline file loading (limited to 40 lines 72 chars wide)
;Mouse Line Select
;Backspace
;Home
;End
;Ctrl + Cursor Right
;Ctrl + Cursor Left
;Shift + Cursor Right
;Shift + Cursor Left
;Shift + Ctrl + Cursor Right
;Shift + Ctrl + Cursor Left
;Page Up
;Page Down
;Ctrl + Home
;Ctrl + End
;Cursor Up
;Cursor Down
;Enter/Return
;Ctrl + C (Single line)
;Ctrl + V (Single Line)
;Loadtext
;Insert/Overwrite
;Insert/Overwrite cursor
;Single line Tab insert (non structured)
;Adjusts to startup resolution

; not finished :
; Bugs!!! :
; Fix addition to cursor on line mouse exit
; Fix Mouse line/row selection (line gets reset to zero, check collision)
;
; Special Edit (vertical Selection)
; Shift + Tab
; Internal Tab handling
; Multiple Line Select
; Tab Multiple Lines
; Shift + Tab multiple Lines + optimalization
; Ctrl + C (Multi line)
; Ctrl + V (Multi line)
; Ctrl + X (Single Line/Multi line)
; Italic/Bold/Underline
; Enter + Splitline
; Mouse to Character collision
; Mouse Selection Automation
; Text Folding
; Folding interface + Hotkeys
; Colored Text
; Inline Icons
; Popup menu
; Auto Completion (list or shaded preview)
; Current Line expand to Visual console
; Horizontal and Vertical Scrollbars
; Data structure optimalization
; Config file based Parsing system
; Save Text
; Sorting routines
; Find/Replace core routines
; Double click keys (Ctrl/shift/Alt)
; Font support
; Dynamic multiple font support
; Inline Images or Ontop Images
; Edit Statistics
; Text Statistics
; Image Buffering
