cmd+c closes dialogs instead of copying text on osx

[Benjamin Nauck]

Description:
cmd+c seems to be a shortcut to cancel instead of copy text in dialogs on osx.

Products Affected:
* eeschema
* pcbnew

Versions:
KiCad 4.0.2-stable, release build
wxWidgets 3.0.2 Unicode and Boost 1.57.0
Mac OS X 10.10.4 (Darwin 14.4.0 x86_64), 64 bit

Steps to reproduce:
1. Create a new file in eeschema
2. Open the add new component-dialog (or any other dialog with input text fields)
3. Enter "copy me if you can" in the filter text field
4. Select the text
5. Press cmd+c

The fifth step closes the dialog instead of copy the text as expected.
Worth noting is that it is possible to copy if you right click the selected text and chose "copy" from the context menu.
It is also possible to paste text using cmd+v

Workaround:
press cmd+x followed by cmd+v to cut and paste instead of copy

Seems to be a wxWidget issue.
More info (and a workaround) is available at http://trac.wxwidgets.org/ticket/15678
Spoiler alert: Dialogs will not close if you supply a label for the cancel button without the ampersand before the C ("Cancel" instead of "&Cancel")
