Ivan Grokhotkov 2510707911 Merge branch 'master' into esp8266
* master: (414 commits)
  Don't export sketch if the underlying core does not support it. Fixes 
  RSyntaxTextArea: using a modified version, tracked at https://github.com/arduino/RSyntaxTextArea. Fixes 
  Updated keywords.txt
  New editor on MacOSX: since CMD+J is known as "jump to selection" and the editor has no such feature, CMD+J is disabled on mac. See 
  Old Preferences class remains for backwards compatibility as a delegate for PreferencesData
  New Preferences window: renders fine on every OS and it's easier to adapt using NetBeans as visual editor. Fixes 
  Remove spawn from exec command
  Removed redundant call to File.deleteIfExists()
  Removed buggy redundant check in FileUtils.deleteIfExists()
  Restored current line/current selected lines display on lower left of the IDE. Fixes 
  Updated cursor.ino
  New editor on MacOSX: restored CMD+E for finding selected text
  New editor on MacOSX: CMD+UP/DOWN moves cursor to start or end of sketch. See 
  New editor on MacOSX: CMD+BACKSPACE deletes current line until cursor position, ALT+BACKSPACE deletes previous word. See 
  ArduinoIDE is in the default package. Removed
  Fixes  :
  Fix Uncategorized warning message
  New editor: ALT+ BACKSPACE deletes next word (OSX only). See 
  New editor: ALT+ UP/DOWN move current line only if "editor.advanced" (hidden pref) is true. Fixes 
  New editor: mark occurrences enable when "editor.advanced" (hidden pref) is true. Fixes

SD card file dump
This example shows how to read a file from the SD card using the
SD library and send it over the serial port.
The circuit:
* SD card attached to SPI bus as follows:
** MOSI - pin 11
** MISO - pin 12
** CLK - pin 13
** CS - pin 4
