SQLStudio: Only display the character/word count of selected text

It's not particularly useful to see the word count of a SQL script,
except for when displaying the number of selected words. This changes
SQLStudio to behave exactly like HackStudio in this regard. We will use
segment 0 to display the selected text stats (if any) and segment 2 for
the cursor position. Segment 1 will be used in an upcoming commit for
the current SQL connection status. We also now handle displaying action
text the same way as HackStudio.
