Nemo terminal 1.0.1

Three key fixes:

1. Terminal clipping outside of the terminal pane is fixed.


2. Safe directory following

    Support has been added for a pre-changedir and a post-changedir string to be sent to the terminal. The default gschema configures these to Ctrl+E and Ctrl+U for pre-changedir, and Ctrl+Y for post-changedir. 

    The net effect is the terminal is always cleared before the directory is changed, and then restored afterwards. This makes it easier and safer to use (commands don't get half run). As a result of this change, the default terminal has been set to /bin/bash in the gsettings schema (since these commands are bash specific).

3. I've improved the language and authorship wording on a bunch of the internal documents since nemo-terminal has improved quite a bit from nautilus-terminal and is no longer a find/replace port.
