* Improved ruby find commands to not include keywords like "def" and "class"
* Saving now jumps back to last position after undoing retab in ruby files
* Added HTML block
* Added HTML mappings to expand word under cursor to opening and closing tag

Moved some navigation-related stuff together.
Added `Matchinglines(pattern)` function that returns a list of lines where
`pattern` is found in a format understood by `lex` and `cex` commands.
Added three new ruby commands that find method, class and module
definitions in a file and ad them to the location list.
FIX: SetWinMinHeight no longer crashes when argument < 0
FIX: <leader>- no longer crashes when already at winminheight=0
ADD: New command Equal makes all windows equally big (and sets
minwinheight to 0 in the process, use <leader>- to reset them)
