v0.1.5

Changes:

• phetch now restores your terminal on exit, like vim.
• Wrapping around to the first nav item now goes home.
• "Page Down" is improved, bugs fixed.
• Some bugs causing your cursor to vanish on exit have been squashed.
• phetch now sends an empty selector to Gopher servers by default. Previously it sent /, which was wrong, according to the RFC.
