[lazarus] findinfiles.diff

[Bob Wingard]

Attached is a patch against, findinfilesdlg.pas, ideprocs.pp, dialogs.pp 
and uniteditor.pp.

Summary:

findinfiles.pas - Add dialogs to uses section, call new function 
SelectDirectory when the browse directory button is pressed, returns 
selected directory. TODO: Add path history and save selections.

ideprocs.pp - Modified the FindInFiles procedure to include some context 
information about the find. The message now includes the next 60 
charaters after the search text.

uniteditor.pp - Ingnore files that are open or part of the project but 
do not exist on disk yet, this would cause lazarus to crash, bad bad. 
Added informational messages to the message window when a search fails. 
TODO: Add progress box with Cancel button.

dialogs.pp - Added the function SelectDirectory, this is same function 
that is in free-clx. Displays a dialog and returns selected directory.

dirsel.lfm, dirsel.lrs, dirsel.pas - Files to implement a work alike for 
the Directory Browser in kylix. Borland used a lot of libc calls in 
thier version, I replace these with regular pascal calls, no chance the 
libc calls would have worked on win32! This dialog is fully functional, 
but is still pretty rough. I will continue to clean it up. I had these 
files in /lazarus/lcl directory. There is not a drive list box, no such 
thing in linux, I will add one later and disable it if on linux or fill 
it with drives if on windows. I need some help with locating images of 
open and closed folders, when I have them I will make the treeview owner 
drawn and spiff it up a bit.

Bob
