0.6.2 Minor updates

This is mostly a community release actually! Fixed a new issues and bugs, notably:

• @slackorama Fixed the bash exiting error for zsh in #191
• @slackorama also fixed #192 which was an out-of-range index error
• @alecjacobson fixed #187 which passed the -i flag only if we are not in the vim shell (so you can use FP from within vim!)
• Few minor fixes like #182, #181
• Expanded line support from @pallavagarwal07 in #178
• @Shenil fixed makefile detection in #173
• and a number of other great fixes!
