File Toolbar: Remove Print action because it's not used very often.
Run and Debug Toolbars: Simplify even more their tooltips
Main Toolbar: Move it to be fourth one from left to right by default

- This way the File toolbar will be the first one to appear, which is consistent
with the vast majority of applications.
Main Toolbar: Only add "External tools" button to it if it has active buttons
Editor: CSS syntax highlighter was buggy (multiline comments) and replaced by a
pygments lexer (CSS syntax highlighting in Spyder will thus require pygments)

Update Issue 1371
Status: Fixed
Run: after deleting a directory set as working directory (Run Settings) and
changing to a new working directory the script won't run

Update Issue 650
Status: Fixed
Object Inspector: Avoid AttributeError if sphinx thread fails.

SphinxThread in the Object Inspector might return an AttributeError if for some
reason the thread fails to return a valid doc string.
Set html_text to something valid at the beginning of the run method instead
of later.

Update Issue 1372
Status: Fixed
Run: added a configuration page to set default Run Settings

Focus was not given to the right plugin when switching between them

- The problem was that refresh_plugin was called twice while switching: once by
the plugin that received focus and once by the one that lost it.
- Now it's just called by the focused plugin.
IPython and External consoles: Update last_console_plugin_focus_was_python in refresh_plugin

- This tracks correctly the currently focused console when there aren't open
consoles in them.
- Useful to print the right warning message for each one.
IPython Console: Improve warning message when there is no open console
Search Toolbar: Hide it by default in all platforms

- Better to be consistent in case the user runs Spyder in several operating
systems.
Merge: Improve default appearance
Run Configuration Page: added the "Always show dialog on a first file run" check box
