Add option to export Bookmarks features

[GaikwadPratik]

This is not a bug but a feature request

Nice utility to have in the belt

Currently you can add a bookmark(color filters, etc) on one machine. Can you please add a way to export them from one machine and import it on another? Currently I have to do this manually on every computer that I use for development.

SnakeTail will apply the default session settings when opening new files. You can just xcopy the session-settings to the machine you like. See also: #106 (comment)
