Branch to enable inter file history tracking.
Able to change view now, uses active_window though..
show_at_center used because it is more prominent
change keys to , (<) for back and . (>) for front and  ; goes to the latest. Seems more natural for me, with the arrow direction, etc
Fix "Show Changes" command, it now shows file basename as well
add a slightly hacky bit of code which opens a file if it has been closed
Fix most bugs
- Remove "Clear Current File" option since it doesnt make as much sense
- Fix clear all history function - needed to add reset to the get_clist function
- disabled/fixed errors with the json stuff
- fixed errors with closed views having no file name
Store and use "point" to move around instead of view. This works nicely if file has been closed, but new bugs seem to have come up
Remove an if check which was causing bugs. Possibly it is to do with per-file stuff
stupid name problem causing the random poping up of old files on different windows. fixed
Add ability to switch back to opened files. Still a little buggy if those files are opened from scratch
