Standardize to camel-case: option to check for updates on launch (#1698)

* Standardize to camel-case: option to check for updates on launch

Updates the "Check for updates on launch" to read instead "Check For Updates On Launch" to be consistent with camel-case options elsewhere in the UI. This time done with manual editing instead of with the Glade app.

* Updated to match general English rules on articles and conjunctions
