Changed wrong translation of identantion

In portuguese, there is no "endentação", but "indentação".

Protect private definitions by the GEANY_PRIVATE macro in headers

In addition, this patch defines the GEANY_PRIVATE macro for the tag
manager library where it wasn't defined before, removes 2 tag manager
headers from distribution as they are not needed by plugins and
in the tag manager changes the docstrings to ordinary comments for
private definitions.
Don't prompt for reload from infobar when there are no unsaved changes

Also warn about losing undo history when there are no changes.
Don't rebuild TagManager workspace tags when quitting

Updating the workspace is useless as the application will be shut down,
and not doing it can save a lot of time (almost 50% speedup quitting an
instance with all Geany source from `src/` open).
Change "replace_and_find_by_default" default to true
Don't alter GeanyEditor internal state in editor_create_widget()

When editor_create_widget() is used on an editor with already existing
widget, don't reset the internal indentation settings of that editor.

Query GdkWindow reference only if available

On startup, the Geany main window doesn't have a GdkWindow yet
(probably because it is not yet mapped). This causes many
'gdkdrawable-win32.c:2013 drawable is not a pixmap or window'
warnings when resolving shortcuts on Windows.
Since we pass the SLR_NO_UI to the Windows API, we probably
don't need the parent hWnd reference at all.

autotools: Properly clean up hacking.html

We don't distribute it, so we need to clean it.
autotools: Remove new Doxygen temporary files
autotools: Only uninstall what we actually installed

Only manually uninstall the files we manually installed, as
uninstall-local might be run in parallel to Automake's own uninstall
targets.

We don't uninstall the directories as some docs seems to suggest
`rmdir` isn't really portable.  Anyway, Automake don't uninstall
directories either so it's not a real problem.

An alternative solution would be to keep the recursive removal of
`$(DOCDIR)` but move it to `uninstall-hook`, which is guaranteed to be
run after other uninstall rules.  However, recursive deletion is not
always sensible as it might remove files we didn't install, e.g. if the
user added them manually.
