Code::Blocks SVN Repo

- updated SVN ignore pattern

* integrate gd_on's external SVN repository for documentation:
** https://svn.code.sf.net/p/codeblocks-gd-user-manual/svn/

* moved old documentation to legacy folder

- moved docs/INSTALL, docs/Makefile.win and docs/README to docs/legacy.

- created directory 'docs/legacy'.

- TODO: Reduce control minimum size (ticket #417).

* CompilerGCC: Add support for MSVC17 (ticket #1352, thanks Martin Strunz).
The xml currently is a copy of the MSVC10 one, it should be expanded with new options (if any).

- Fix translation of "Highlighted Occurrences" pane not appearing.

* TODO: Fix panel not filling correctly (ticket #1364).
The selected types array must be initialized earlier.
Simplify management of said array and selection dialog.

- Debugger: Prevent GDB from generating ANSI escape sequences (ticket #1366).
GDB 8.2 (and newer) generates coloured output using this sequences
and they interfere with output parsing.
