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.
### Problem description
Messages in the TCP tool were only visible as a text string in the
messages list and unable to be opened in the hex view.
There was also no way to send data other than as a typed in text string
in the input field.
### Implementation description
* Added the ability to double-click on a message in the messages list to
open it in a provider tab.
* Added a new button to the client tab to send the current provider to
the connected server.
* Updated the list look to show the message index in a column

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.
