Changed cvskill env left-column to vertical top

[caldempsey]

In line with issue #136 a new column type "K" was created to vertically align the left-hand side of the text. I have also made alterations from L{\textwidth * \real{0.9}}} to prevent text overflow.

Agree with this idea. Hope this can be merged ;)

I just manually applied these changes and it works fine. Wondering why it hasn't been merged...
