Lose the project/class browser

[danielrcollins1]

Here's a UI problem:

• Open Dev-C++
• See project/class browser on left
• Manually resize that browser panel to zero (shrink all the way to left-hand edge of window)
• Now you can't grab that browser panel to resize it back into view (any attempt just grabs the application window edge and resizes that instead).

A workaround in this state is:

• In View > Project/Class Browser, toggle the switch off and then on
• Now you can grab the left edge and recover the project/class browser panel

That's obviously unintuitive and hard to guess at; ideally the project/class browser would always be grabbable when the view setting is on. Small downside is in that particular hidden state, resizing the application window from the left wouldn't be viable, but that will be much more obvious in how to fix (resize project browser once, then adjust application window).
