Update tip of the day, fix invalid menu items, shortcuts, typos

Hi IntelliJ team,

I went through all tip of the day of IntelliJ Ultimate 12.1.1 and corrected a few mistakes.
Unfortunately a lot of images in the tips aren't displayed if I build IntelliJ Community Edition by myself 
Environment: Windows 7 32 Bit, Java 6/7, latest source version from github
Failed: images/ctrl_shift_i_lookup.gif
Success: images/properties_completion.gif

The images are shown correctly if I use the packaged version from Jetbrains. Is this normal? 

It would be nice if you would include this patch in one of the following releases.

Best regards

Josef
