1.0.0

The first stable release of ruby-lint. The 1.0 series will not introduce any
breaking API changes. The changes in this particular release are fairly small.
Initially I wanted to include the ability to skip analysis for certain
constants but I've decided to hold this off until the next release as I'm not
yet sure how I envision this feature.

Having said that, this release contains the following noteworthy changes:

• Column numbers now start from 1 instead of 0, something I completely
  overlooked until now.
• Performance of RubyLint::FileScanner#scan has been improved significantly
  (more on this below).
• ruby-lint can now run analysis on an entire directory instead of only
  operating on individual files.
• Support for Range instances when building definitions.
• Various extra stdlib definitions have been added.
• Support for conditional code analysis (see below).

FileScanner Performance

The performance of RubyLint::FileScanner#scan has been improved
significantly. In previous versions a call to Dir.glob was made every time
ruby-lint tried to find a constant from the local file system. This process has
been improved by retrieving all Ruby files at once and caching the results.
When performing analysis on lib/ruby-lint/virtual_machine.rb this change lead
to a reduction in execution time of about 400 milliseconds.

See http://git.io/Q5s8Lw for a more detailed description of this change.

Conditional Code Analysis

This new feature allows analysis classes themselves to determine whether or not
they should be used. This can be used to write analysis code that only runs on
Rspec files for example.

Currently ruby-lint doesn't ship with any analysis classes that use this
feature but I plan to add these in the future.
