Reorganized source code into files named in the fashion of imhex and
split large functions into smaller ones. Moved all function definitions
out of the header except for one-liners. All variable types were
switched to use imHex standard (u8,...) and removed duplicated functions
that were needed when the text editor was isolated.
Minor improvements to find/replace while making sure they still worked
with utf-8 chars.
Added the ui namespace and broke the main rendering function into a set
of smaller functions. Reorganized the header code separating functions
into rough groups that eventually will be in separate files.
Also fixes two bugs:
1) error messages not staying visible
2) uncaught exception when struct name is duplicated.
A lot of the code using coordinates for start and end has been moved to
use Selections instead. Created more string manipulation code that uses
utf8 indices aka Coordinates directly. This makes implementing editing
functions easier by not having to go back and forth from string indices
to char indices and back. Currently, the substring, erase and []
operator support coordinates and str indices.
