Merge pull request #16 from saschpe/master

Several fixes
Fix test path issues.

Find fixtures when invoke via "python lesscpy/tests/__main__.py" and
generate better names for 'less' and 'issues' tests.
Verbose testsuite runs
Convert to int when using round(), ceil() or floor()

round(1.2px) is expected return '1px', not '1.0px'
lighten(#555, 10%) should return #6f6f6f, not #6e6e6e

Matches lessc's output.
Use precise grid margin values

This is a bit controversial since it's different from lessc output.
Still, it's correct since 87.8+27+1.7 == 116.5
(offset3_margin-left + span1_width + span_margin-left ==
offset4_margin-left)
Implement SVG stylesheets.

Including SVG-specific elements and attributes and an initial
testsuite.
Allow camel-case DOM elements defined in SVG-1.1

The SVG standard defines several DOM elements in camel-case (namely
textPath, altGlyph, altGlyphDef, altGlyphItem and glyphRef). Even though
most browser also accept lower-case, the lexer should take this into
account.
Bump version to 0.9i
